I'm working on texture mapping the walls of a simple maze game. The maze walls are basically boxes, but each is of a different length and width (heights are the same). I don't have an array of corresponding texture coordinates for each vertex. Is there any way I can use the glTexGen() function to tile the textures simply and easily, or is there some algorithm for calculating the tex coordinates? For now I'm using glTexGen func, but it makes every wall different. Also, I'm not sure what array to pass to glTexCoordPointer. Currently I'm just using texCoords = { 0.0, 0.0, 1.0, 0.0, 1.0, 1.0, 0.0, 1.0}. Is this wrong?? Here's the relevant code. // in my CreateTextures() function glBindTexture(GL_TEXTURE_2D, textureNames[texID]); gluBuild2DMipmaps(GL_TEXTURE_2D, internalFormat, texti->width, texti->height, GL_RGB, GL_UNSIGNED_BYTE, texti->data); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST_MIPMAP_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR); glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR); glEnable(GL_TEXTURE_GEN_S); glEnable(GL_TEXTURE_GEN_T); // in my Draw() function glBindTexture(GL_TEXTURE_2D, texture->getTextureID()); glTexCoordPointer(2, GL_FLOAT, 0, texCoords); glVertexPointer(3, GL_FLOAT, 0, vertices); for (int i = 0; i < nFaces; i++) { glDrawElements(GL_POLYGON, nVPerFace, GL_UNSIGNED_INT, indices[i]); } Thank you!!
