Title Body

I'm trying to figure out texture mapping in OpenGL and I can't get a simple example to work. The polygon is being drawn, though it's not textured but just a solid color. Also the bitmap is being loaded correctly into sprite1[] as I was successfully using glDrawPixels up til now. I use glGenTextures to get my tex name, but I notice it doesn't change texName1; this GLuint is whatever I initialize it to, even after the call to glGenTextures... I have enabled GL_TEXTURE_2D. Heres the code: GLuint texName1 = 0; glGenTextures(1, &texName1); glBindTexture(GL_TEXTURE_2D, texName1); glPixelStorei(GL_UNPACK_ALIGNMENT, 1); 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_MAG_FILTER, GL_LINEAR); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); glTexImage2D(GL_TEXTURE_2D, 0, GL_BGRA_EXT, sprite1[18], sprite1[22], 0, GL_BGRA_EXT, GL_UNSIGNED_BYTE, &sprite1[54]); glColor3f(1, 1, 0); glBindTexture(GL_TEXTURE_2D, texName1); glBegin(GL_QUADS); glTexCoord2f (0.0, 0.0); glVertex3f (0.0, 0.0, -5.0f); glTexCoord2f (1.0, 0.0); glVertex3f (.5, 0.0, -5.0f); glTexCoord2f (1.0, 1.0); glVertex3f (.5, .5, -5.0f); glTexCoord2f (0.0, 1.0); glVertex3f (0.0, .5, -5.0f); glEnd(); UPDATE: I'm at a loss. Here's everything I've tried: Turns out I was initializing my texture before OGL was initialized. The texture is initialized (glGenTextures->glTexImage2D) in a class constructor and drawn (glBegin->glEnd) in a member function that is called every frame. genTextures appears to be working correctly now and I'm getting a name of 1. Every possible combination of GL_RGBA8, GL_BGRA_EXT (GL_BGRA doesn't work on my system; I need the _EXT), and I even removed the alpha ch
