+INTRODUCTION

+

+A generic, configurable software implementation of GL transformation &

+lighting.

+

+This module provides an implementation of the routines required by the

+'vtxfmt' mechanism of core mesa for tnl functionality in all

+combinations of compile and execute modes.

+

+Most current drivers use the tnl module exclusively to provide this

+functionality, though there is an experimental alternate

+implementation provided by the tnl_dd/t_dd_imm_* files which can

+handle a small subset of GL states in execute mode only.

+

+

+STATE

+

+To create and destroy the module:

+

+	GLboolean _tnl_CreateContext( struct gl_context *ctx );

+	void _tnl_DestroyContext( struct gl_context *ctx );

+

+The module is not active by default, and must be installed by calling

+_tnl_Wakeup().  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( struct gl_context *ctx );

+	void _tnl_wakeup_save_exec( struct gl_context *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( struct gl_context *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( struct gl_context *ctx, GLboolean flag );

+

+	- Direct the default vertex transformation stage to

+          produce/not produce projected clip coordinates.

+	  

+extern void

+_tnl_need_dlist_loopback( struct gl_context *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( struct gl_context *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)( struct gl_context *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.

+ *
