This module provides the fallback -paths for rasterization operations and states that aren't accelerated -in hardware drivers, and as the full rasterization engine in software -drivers. - -The swrast module 'stands alone', relying only on interfaces to core -mesa and it's own driver interface. It knows nothing about the tnl or -other modules, allowing it to be used for fallback paths in future tnl -schemes without modification. - -As well as providing triangle/line/point rasterization functionality, -the module provides implementations of the pixel operations -(ReadPixels, etc), and texture operations (CopyTexSubImage) which may -be plugged in to the core Mesa driver interface where accelerated -versions of these operations are unavailable. - - -STATE - -To create and destroy the module: - - GLboolean _swrast_CreateContext( GLcontext *ctx ); - void _swrast_DestroyContext( GLcontext *ctx ); - -This module tracks state changes internally and maintains derived -values based on the current state. For this to work, the driver -ensure the following funciton is called whenever the state changes and -the swsetup module is 'awake': - - void _swrast_InvalidateState( GLcontext *ctx, GLuint new_state ); - -There is no explicit call to put the swrast module to sleep. - - -CUSTOMIZATION - - void (*choose_point)( GLcontext * ); - void (*choose_line)( GLcontext * ); - void (*choose_triangle)( GLcontext * ); - -Drivers may add additional triangle/line/point functions to swrast by -overriding these functions. It is necessary for the driver to be very -careful that it doesn't return an inappropriate function, eg a -rasterization function in feedback mode. See the X11 driver for -examples. - -DRIVER INTERFACE - -The swrast device driver provides swrast primarily with span- and -pixel- level interfaces to a framebuffer, with a few additional hooks -for locking and setting the read buffer. - -See the definition of struct swrast_device_driver in swrast.h.
