I\'m about to go mad. I c开发者_如何学运维ant for the life of me figure out texture coords. I have a Octahedron defined by the 8 triangles below. I want to map a texture of the earth on it.See the tex
What i\'m trying to do is making a \"light projector\" with visible ray(like with fog) also called volumetric light;
I have been tryingimprove the performance of my game on iphone. Most of the cases, I do my all texture loading just before rendering the current开发者_如何学运维 frame. That makes big jerk in the fram
I am trying to do something with Ogre using 3D textures. I would like to update a 3D-texture by going through it slice-by-slice and recalculating the color val开发者_如何学Goues. However, in each step
When I load textures from images normally, they are upside down because 开发者_JAVA百科of OpenGL\'s coordinate system. What would be the best way to flip them?
Do I have to set up my gl context in a certain way to bind textures. I\'m following a tutorial. I start by doing:
I have a very complex 3d surface I need to apply a 2d mesh to. What I need is something like the Solidworks Wrap tool : http://www.rickyjordan.com/2009/01/the-solidworks-secret-weapon-the-wrap-tool.ht
My Vertex Buffer Object code is supposed to render textures nicely but instead the textures are being rendered oddly with some triangle shapes.
I am making a 2D game with OpenGL. I would like to speed up my texture drawing by using VBOs. Currently I am using the immediate mode. I am generating my own coordina开发者_如何学Gotes when I rotate
I would like to combine bitmaps to one texture and apply it to a cylindric primitive. The cylinder will be rotating or better: the texture should moving along the cylindric-surface and therefor you sh
