Detailed Description

brush model loading

Definition in file r_model_brush.c.

Function Documentation

static void R_LoadBspVertexArrays ( model_t * mod ) [static]

Puts the map data into buffers.

See also:: R_ModAddMapTile

Note:: Shift the verts after the texcoords for diffuse and lightmap are loaded

See also:: R_ModShiftTile

Todo:

Don't use the buffers from r_state here - they might overflow

Decrease MAX_GL_ARRAY_LENGTH to 32768 again when this is fixed

void R_ModBeginLoading	(	const char *	tiles,
		qboolean	day,
		const char *	pos,
		const char *	mapName
	)

Specifies the model that will be used as the world.

Parameters:

`[in]`	tiles	The tiles string can be only one map or a list of space seperated map tiles for random assembly. In case of random assembly we also need the `pos` string. Every tile needs an entry in the `pos` string, too.
`[in]`	day	Load the day lightmap
`[in]`	pos	In case of a random map assembly this is the string that holds the world grid positions of the tiles. The positions are x, y and z values. They are just written one after another for every tile in the `tiles` string and every of the three components must exists for every tile.
`[in]`	mapName	The mapname that the get from the server (used to identify the correct name for the materials in case of a random assembly).

See also:: R_ModAddMapTile; CM_LoadMap

Note:: This function is called for listen servers, too. This loads the bsp struct for rendering it. The CM_LoadMap code only loads the collision and pathfinding stuff.

static void R_ModShiftTile ( void ) [static]

Shift the verts for map assemblies.

Note:: This is needed because you want to place a bsp file to a given position on the grid - see R_ModAddMapTile for the shift vector calculation This vector differs for every map - and depends on the grid position the bsp map tile is placed in the world; Call this after the buffers were generated in R_LoadBspVertexArrays
