Function Documentation

void R_DrawModelDirect	(	modelInfo_t *	mi,
		modelInfo_t *	pmi,
		const char *	tagname
	)

Draws a model in 2d mode (for rendering model data from the ui)

Parameters

[in,out]	mi	All the needed model information to render the model
[in,out]	pmi	The model information of the parent model. This is used in those cases, where the model that should get rendered here is placed relativly to an already existing model in the world.
[in]	tagname	If a parent model is given, a tagname is given in most cases, too. It's used to transform the model location relative to the parent model location again. E.g. a tagname of tag_rweapon will transform the location to the right hand of an actor.

int R_GetTagIndexByName	(	const model_t *	mod,
		const char *	tagName
	)

Searches the tag data for the given name.

Parameters

[in]	mod	The model to search the tag data. Can be nullptr
[in]	tagName	The name of the tag to get the matrix for. Might not be nullptr

Returns

-1 if no tag with the given name was found

bool R_GetTagMatrix	(	const model_t *	mod,
		const char *	tagName,
		int	frame,
		float	matrix[16]
	)

Parameters

[in]	mod	The model to get the tag transformation matrix for
[in]	tagName	The name of the tag to get the transformation matrix for
[in]	frame	The frame of the tag to get the transformation matrix for
[out]	matrix	The transformation matrix

Returns

false if the tag name for the given model wasn't found, true if the matrix was filled.

void R_ModelAutoScale	(	const vec2_t	boxSize,
		modelInfo_t *	mi,
		vec3_t	scale,
		vec3_t	center
	)

Compute scale and center for a model info data structure.

Parameters

[in]	boxSize	The size the model should fit into
[in,out]	mi	The model info that contains the model that should be scaled
[out]	scale	The scale vector
[out]	center	The center of the model (center of the model's bounding box)

Note

The scale and center vectors are parameters here because the modelInfo_t struct only holds pointers to the vectors.

Todo:

Take the rotation info from modelInfo_t into account
