Paint.NET :: Creating Height / Parallax Maps?
Apr 23, 2012
Basically I want to create a heightmap from a colormap (a game texture). Heightmaps are used by my shader to add additional detail to surfaces (see herefor a such a surface). This technique is called Relief Bump Mapping and produces pretty cool result if the shader gets a decent heightmap.
My problem is that I only have colormaps and want to create the heightmaps in Paint.Net. So far I simply played around with the contrast and and brightness of the picture, but the results are not perfect...
I uploaded some scaled down pictures which illustrate my problem a bit better:
This is my colormap texture:
If I am using my technique (changing contrasts and brightness) I don't get good results.
The red parts show the most problematic zones of the heightmaps. Since black means no height and white means height, these regions don't contain any height informations...I already thought about using a edgre filter, but the built in one doesn't seem to be very good.

Ideally I would like to use the nVidia normal map filter plugin - it's for Photoshop, and although, apparently, you can use some photoshop plugins, this one does not seem to work.
First question - is there a way to use the nVidia plugin?
Next - is there a Corel way?
I have created my own greyscale heightmap images and I can export red channel for alpha. Then I flood fill the red channel black and the blue channel white and export the RGB as the colour part. Creating a dds image gives me a pseudo bumpmap
BUT
Whenever I use this kind of bumpmap I get the effect I want on the aircraft models, but for some reason, "my" bumpmaps seem to remove the polygon smoothing of the 3D models so that when I "fly" the aircraft, I actually see the polygons instead of the smotthed mdl surface.This photbucket link shows what I mean.
The left hand image shows the original bumpmap on the original model. The next image shows modified artwork on the same model. Then I have change to a "D-i-Y" bumpmap and the last two show that although the desired bumps are there, I now have the wireframe polygons visible.

I am currently rendering 3D models' height maps using a gradient ramp with an UVW map. The models can be trees, characters etc, it's not terrain.
I would really like to know how to use all 16,777,216 colors so that my height maps have that many different values.
So far I only managed to used the gradient ramp and gain a total of 766 different height values. I use 4 colors in the gradient, here is how:
- First gradient ramp color is full black, and placed at position 0
- Second one is at position 33 and is RGB(0, 0, 255)
- Third one is at position 67 and is RGB(0, 255, 255)
- Fourth one is full white at position 100
This totals 766 different height values retrieved using R+G+B (0 to 255+255+255). What should I do to use the full 16 millions colors?
With my current gradient ramp I cannot use the whole RGB value (i.e. a 24 bits integer, 0 - 16,777,215). I have to separate channels into 8 bits integers (0-255), because with 24 bits a higher value is not necessarily representing a higher height. That's due to the way my gradient is made, and I couldn't find better than what I use.

I'm trying to simulate water in a community game I am building. I need to create a good number of frames to test one method, but I don't know how to go about it. Since these would be height (bump) maps, color is really not necessary. Basically, I need to create frame by frame to simulate water. The game engine will actually paste them together to form the animation.
The problem is I just don't know how I can go about creating the ripples frame by frame. I'd probably like to try to make 50 frames or so. I know about the ripple filters, but how would I use them to create a series of frames?

After just reading all 146 messages in the topic, "No more ImageReady in CS3 - VERY FRUSTRATING", I am seriously bummed, but left with unanswered questions.
Specifically, has anyone found a cheap, practical alternative for creating simple image maps with polygonal click regions? I want to create an actual map, where you click on a city name and go to a web page on that city. Rectangles do not work, as the real world regions are not shaped that way -- it has to be polygons. Nor do I want the map to be physically sliced apart and reassembled with table elements. I just want to use the HTML map
and area tags.
Photoshop 7 (my last version) could do this simple, useful task. My Photoshop CS3 "upgrade" cannot.
creates simple map & area image maps -- or perhaps an add-in or standalone? Something other than a $300 piece of otherwise useless (for my purposes) bloatware.

I want to write the words HAPPY and BIRTHDAY underneath each other so that the word HAPPY takes up the the same width as the word BIRTHDAY. I also want to make the HAPPY twice as tall as the word BIRTHDAY.
Do I need to adjust the spacing and/or width for each individual letter? I'm guessing I can make the HAPPY taller by some kind of stretching tool?

I've been using Blender a lot recently, and, not wanting to front the money to buy a Normal Map generation program or (oh dear) use GIMP of all things, I decided to try creating a Normal Map in Paint.NET.
What is a Normal Map, you ask? Normal Maps are images that are used in conjunction with a texture to give the texture false 'depth', allowing, say, light to shine onto the bricks in a texture while not getting into the cracks between, or making light come from a specific side.
The original texture:
The normal map:
The result:
Not the best, as you can clearly see.
How could I make improvements? Is this even practical?

The starting point:
I have a JPG image of a battlefield wherein the height contours in feet are marked as faint lines (like a closed contour line for 390 feet, another for 420 feet, etc etc.)
The desired final product in Photoshop:
A grayscale RAW document that shows the height variations in gray tones.
Low lying troughs need to be darker and higher elevations need to be lighter.
See picture below for example:
I am ignoring the roads and other features in the battlefield.
All I am interested is the technique of converting the height contours into a smoothly varying grayscale image.
I am a complete Neanderthal when it comes to Photoshop. I do have a copy of Adobe Photoshop CS3 on my PC.
I have been toying around with the package on and off. But nothing useful has come out yet.
Now to my specific questions
*How do I bring in the height contours into Photoshop? I have tried the magnetic lasso tool and able to trace a height contour with good fidelity.
I am kind of stuck at this point. Do I save the selection to a new layer? Do I thus create one layer for each of the height contours?
Say one layer for the all the 390 feet contours, another layer for the 420 feet contours, one more for the 360 feet contours etc etc?
*Assume that I have somehow brought in all the height contours successfully into a new Photoshop document.
How do I create a gradient effect between the contours?
The lowest height in the map is 300 feet and the highest areas are at 480 feet.
Thus the area enclosed by the 300 feet contour lines needs to be darkest (pitch black) and the area enclosed by the 480 feet contour lines needs to be lightest (pure white).
The areas in between need to go progressively from dark to light shade.
How do I achieve this?
*Assume that I have created now a PSD document that has these smoothly varying grayscales. How do I convert this to a RAW image?

Our company logo exists as an outlined .eps file. Wouldn't I simply send the logo to the printer and have them resize it as needed? How do you set up a file with no height designation?

I would like to know if I can import my AutoCAD 3d file into 3DS MAX, with the lighting maps and material maps intact. This is because I am doing my thesis on AutoCAD 2011 but I would like to use 3DS Max to do a walk through video.

Texturing an .obj file with multiple maps keeps getting overlap when I paint on the figure.
I am very new to 3D Painting in Photoshop but I am nominally knowledgeable of Photoshop in general for 2D work. I exported the Genesis figure from DAZ Studio into an .obj file and painted on it in Photoshop 5.5.
When I paint on his face, other marks show up on his torso and thigh and eyes, even. It is like all of the diffuse maps are "stacked upon one another" (though not in layers, just one one layer.)

I am creating an upper cabinet which has a fixed height but you can select different widths. What our firm does is also list the size of the cabinet. What I would like to do is make this font some sort of preset attribute and control it with the visibility states. I also want to control the font height by the scale of the drawing. my question is I if its possible and how? I've attached what I have thus far. The attribute is in teh top right corner and is justified as top right. The only way I can get this to work is if I manually adjust the font after its inserted into the drawing.

I'm using the Parallax function from Edge Commons to build a parallax website.
It looks great on all browsers, and most mobile devices, except everything Apple iOS.
On any device running iOS, there's no animation when scrolling.
I know that basic parallax scrolling isn't supported in iOS (yet), but would there be some workaround using touch functions?
The following code works just as well as the Edge Commons function by the way, may be this could be modified to work with iOS?
$(window).scroll(function(e){
var scrollTop = $(window).scrollTop();
var docHeight = $(document).height();
var winHeight = $(window).height();
var scrollPercent = (scrollTop) / (docHeight - winHeight);
var percentageScrolled = (scrollPercent*100)/100;
var pos = Math.round(percentageScrolled*sym.getDuration());
sym.stop(pos)
});

I have a *.png picture with a file size of 5.8 MB a height of 39920 pixels and a width of 1020pixels.
When I try to drag& drop this picture from WinExplorer onto a X2 PSP installation then PSP tells me: "This is not a valid PNG file"
This *.png picture can be displayed without problems with other viewers. So its a problem of PSP.
How can I let PSP load successfully this picture?
I have a memory of 4Gb and running WIn7 pro 64bit. So hardware shouldn't be a problem too.

I am trying to create a script (that I can run on a batch of images) that will resize the images to a set width but will maintain the proper aspect ratio of the images. There are many images and they are all different dimensions.
I want to resize them for webpages to a standard width (300) and have the height be automatically adjusted to the new width (proper aspect ratio).
When I try to create the script, it automatically uses the aspect ratio height of the image that was used to create the script.
When it runs on additional images it automatically sets their height to the height of the first image (used to create the script). As all of the images have different dimensions, the end result is wrong.
Is there a way to write the script so that it will maintain the proper aspect ratio of multiple images, all with different dimensions?

how to apply a filter to a Floor Plan to color code my Walls by Unconnected Height for coordination purposes?
I want to disseminate which walls are currently modeled to deck and which ones stop short so I can selectively coordinate this.
This seems completely logical, but I don't see the option to allow this.
Why does Revit allow me to schedule the Length of a Wall, but not it's Height - am I missing something?

I have some photos that might look good as a tryptich or "broken-up" into even more components of equal size and then framed separately. Is there a relatively easy way to do this with PSP X5? I saw a youtube tutorial on doing this in Photoshop that included overlaying some guide lines over the image and then repeatedly cropping and saving the resulting image.
I haven't found the right tool to do this in X5, though I assume such a thing exists. And I'm not sure how to describe the thing to file search. I've tried freehand cropping, but it is pretty inexact. Is there a way to get a more accurate sizing?
Also to those who have done this before. How important is accurate sizing of the component images? Is "close - enough" good enough? I keep wishing there was a wizard available where I could specify the number of rows and columns a photo could be broken up into and then have the wizard do the cropping and auto saving of the resulting image.

I have an HP Pavilion dv7 laptop with preinstalled PS Photo Pro X3, so no CD/DVD. I need to reformat my hard drive to make it dual boot Win/Mac but I would then like to reinstall PSP X3. Is it possible to create installable CDs/DVDs from the preinstalled (or downloaded?) version? If it's not possible, am I entitled to CDs/DVDs from Corel, or can I download and use my current serial number/registration info to activate the product?

So my question is what would be the best route for creating this effect without the use of flash? (I expect that there is going to have to be code thats going to go into my website for this to happen whether that be html or javascript)
