Hardware Transform and Lighting
Hardware Transform and Lighting (Hardware T&L) are functions that are carried out directly by the video hardware. Transform and Lighting carry out the process of generating a 3D scene from supplied data, our 3D 'world'.
The first functional unit, transformation, is a ‘geometry engine' that converts or that transforms the 3D coordinates of the world into 2D coordinates. This transformation must be completed because the monitor where the 3D world is viewed is a 2D device.
Additionally, transforming 3D coordinates into 2D coordinates, the geometry engine can be used to generate lighting information for the world, store information about light sources, and calculate the amount of light that each source casts on any point in the world.
Supported video hardware
Halo: Combat Evolved requires access to a minimum of 32 MB of memory for video display.
