I\'ve got a working GLSL shader that runs on the PC using a OpenGL ES simulator and in the iOS simulator.When I run it on a real iPad (running iOS v4.2) it doesn\'t render.The shader compiles and link
How to pause a shader in frame in order to not开发者_Python百科 influence to other render parts?Unless I misunderstood you want to switch back to fixed pipeline functionality for rendering some other
I read from the OpenG开发者_JS百科L Wiki that current Modern GPUs are only programmable using shaders.
I\'ve been doing graphic programming using the fixed pipeline of OpenGL after learning in school and I\'m thinking of starting to learn GLSL. However I\'m using Intel GMA X3100 card on Windows and it
How do I compute an eye space coordinate from w开发者_如何学JAVAindow space (pixel in the frame buffer) coordinates + pixel depth value in GLSL please (gluUnproject in GLSL so to speak)?Looks to be du
How to set several texture coordin开发者_开发百科ates for one vertex?In Immediate Mode you use glMultiTexCoord for this: http://www.opengl.org/sdk/docs/man/xhtml/glMultiTexCoord.xml
Currently I\'m using glUseProgramObjectARB(ProgramObject); and glUseProgramObjectARB(0); But it doesn\'t switch back properly，and gives me an “invalid operation glError” along these lines
I started moving one of my projects away from fixed pipeline, so to try things out I tried to write a shader that would simply pass the OpenGL matrices and transform the vertex with that and then star
I want to project a texture on to a wall or any object.I modified this tutorial\'s shaders as follows based on this Cg projective texture mapping tutorial (ctrl-f \"9.3\") but I get a blank, white can
