Applying textures in OpenGL involves the following steps:
| Enable texturing | glEnable(GL_TEXTURE_2D) |
| Define a texture |
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)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height,
0, GL_RGB, GL_UNSIGNED_BYTE, imageData)
|
| Assign texture coordinates | glTexCoord2f(0,0) glVertex3f(-1.0, -1.0, 0.0) glTexCoord2f(1,0) glVertex3f(1.0, -1.0, 0.0) |
