This function installs internal tnl functions into all -the vtxfmt dispatch hooks, thus taking over the task of transformation -and lighting entirely: - - void _tnl_wakeup_exec( GLcontext *ctx ); - void _tnl_wakeup_save_exec( 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 _tnl_InvalidateState( GLcontext *ctx, GLuint new_state ); - -There is no explicit call to put the tnl module to sleep. Simply -install other function pointers into all the vtxfmt dispatch slots, -and (optionally) cease calling _tnl_InvalidateState(). - -CUSTOMIZATION - -The module provides customizability through several mechanisms. The -most important is by allowing drivers to specify the pipeline through -which vertex data is passed, including its eventual transfer to -rasterization hardware (or software). - -The default pipeline is specified in t_pipeline.c, and is usually a -starting point for driver pipelines. Some drivers will remove a stage -where hardware provides support for the implemented operation (for -instance fog where per-pixel hardware fog is available, as in the dri -tdfx driver), or add stages to shortcircuit latter operations (for -example taking advantage of hardware support for strips and other -higher-level primitives (for example the radeon driver). - -In addition, the following functions provide further tweaks: - -extern void -_tnl_need_projected_coords( GLcontext *ctx, GLboolean flag ); - - - Direct the default vertex transformation stage to - produce/not produce projected clip coordinates. - -extern void -_tnl_need_dlist_loopback( GLcontext *ctx, GLboolean flag ); - - - Direct the display list component of the tnl module to - replay display lists as 'glVertex' type calls, rather than - passing the display list data directly into the tnl pipeline - mechanism. - - This allows display lists to be replayed by the tnl module - even when the module is not strictly active. - - -extern void -_tnl_need_dlist_norm_lengths( GLcontext *ctx, GLboolean flag ); - - - Direct the display list component to enable/disable caching - 1/length values for display list normals. Doing so is - ususally helpful when lighting is performed in software, but - wasteful otherwise. - - -DRIVER INTERFACE - -The module itself offers a minimal driver interface: - - void (*RunPipeline)( GLcontext *ctx ); - -Normally this is set to _tnl_RunPipeline(), however the driver can use -this hook to wrap checks or other code around this call. - -In addition, the driver interface for the default render pipeline -stage is housed in the tnl context struct (this could be cleaner). - - -RENDER DRIVER INTERFACE - -See t_context.h for the definition and explanation of this.
