static NvModelGL* NvModelGL::CreateFromModel

(

NvModel *

model

)

[static]

Create a renderable model from an unoptimized NvModel object.

Parameters:

[in]

model

the unoptimized model to be converted

Returns:

a pointer to the new model

static NvModelGL* NvModelGL::CreateFromObj	(	uint8_t *	data,
		float	scale,
		bool	computeNormals = false,
		bool	computeTangents = false
	)			[static]

Create a renderable model from OBJ data.

Parameters:

[in]	data	pointer to OBJ file data
[in]	scale	the target radius to which we want the model scaled, or <0 if no scaling should be done
[in]	computeNormals	indicate whether per-vertex normals should be estimated and added
[in]	computeTangents	indicate whether per-vertex tangent vectors should be estimated and added

Returns:

a pointer to the new model

static NvModelGL* NvModelGL::CreateFromPreprocessed

(

uint8_t *

data

)

[static]

Create a renderable model from a preprocessed "NVM" file, which is much faster and more efficient to load than OBJ.

Parameters:

[in]

data

pointer to NVM file data

Returns:

a pointer to the new model
