Support / Re: Remove texture
« on: May 12, 2013, 01:52:20 am »
I have problem with setPolygonTexture method. This code is performed in IRenderHook.setCurrentObject3D(). I do not call strip() anywhere. The object is composed of two triangles. Where could the problem be?

Code: [Select]
PolygonManager pm = obj.getPolygonManager();
int difuseTextureID = pm.getPolygonTexture(0);
TextureInfo ti = new TextureInfo(difuseTextureID);
ti.add(normalTextureID, TextureInfo.MODE_ADD);
ti.add(shadowTextureID, TextureInfo.MODE_ADD);
int maxID = pm.getMaxPolygonID();
for (int i = 0; i < maxID; i++)
pm.setPolygonTexture(i, ti);
Code: [Select]

Nice project, I hope you successfully complete undergraduate exams ;)

Fine, could you add method for change texture id in specific stage? This is needed

Support / Shader uniforms
« on: May 10, 2013, 09:04:49 pm »
What differences are between these two methods? GLSLShader.setUniform(String name, float[] array) and GLSLShader.setFloatArrayUniform(...). I think you have added a second one for me, but I can not remember why. I came across a strange behavior. When I set number into shader, performance goes up from 33 to 44 fps. But if I set this number into array  uniform, fps is 33. How is this possible? I've never seen such a large drop in the fps for one array uniform ???

Is expensive to set on every object 4 texture stages and uses less?

Please, could you add method for remove texture from PolygonManager (PolygonManager.removeTexture(int stage))? So each textures on higher stares will be moved down.
It would be helpful if the method TextureManager.addTexture(...) return texture id.

Interesting video presentation about mobile shader, how optimize,...

This is very simple application for merge normal and offset texture. If someone wants, I can extend the application of a few functions. Application require .NET Framework 4.5.



Download

update: I've added the ability to change the texture size.



update:
   - support for opening files by drag and drop
   - added ability to choose the color channel of offset texture
   - new option menu
   - added progress bar
   - added ability to change size and interpolation of merged texture
   - fixed some small bugs

update:
   - renamed textures in merge tab
   - drag and drop across tabs (merge result -> resize input)
   - drag and drop to save texture
   - fixed black dot bug on some textures

update:
   - added application icon
   - support ctrl + s to save result

Support / Re: Shader limitation
« on: May 06, 2013, 05:21:44 pm »
OK, I just do not like, when is anything in my code limited from unknown reasons (I have to also limit number of lights in shader). Anyway, more than 8 per-pixel lights are to expensive for mobile devices, but if I ever need more, I can simple manage myself.

edit: You probably know how I generate light shader. Will be faster (+0.5ms) if I manage lights myself? I need to speed up the rendering process. Real map is running on SGS3 about 40fps and on Tegra3 and other lower devices it is unplayable...

...If you write your own shader, you can set as many lights as you want...
Are you sure? More than 8 lights do not work (9th light does nothing)

I probably looked at another number, maybe at texture processor units. No, but every array for light is length of 8 (ex. uniform vec3 lightPositions[8]). Ok, thanks for info.

Vainly trying to figure out why everyone are using normal mapping in tangent space instead of object space. Object space is faster and less memory-intensive. Or what is main differences?
