'''Projective texture-mapping''' is a method of texture mapping described that allows a textured image to be projected onto a scene as if by a slide projector. Projective texture mapping is useful in a variety of lighting techniques, including shadow mapping. Since its inception its functionality has been included into the OpenGL and DirectX SDK. Projective texture mapping refers both to the way texture coordinates are assigned to vertices, and the way they are computed during rasterization of primitives. Projective texture mapping has also been used in the large scale mapping of buildings allowing for matching up of the picture with a 3D scene. The current implimention of Projective texture mapping is avalible in the Nvidia SDK.

'''Projective texture-mapping''' is when a computer generated model is given color. The artist applies a [[texture]] color or print to the model. When the model is later rendered, the texture shows up stretched over the model.
