Typedef Documentation

nvwarpFaceDescription_t

typedef struct nvwarpFaceDescription_t nvwarpFaceDescription_t

There is a description for each of the 6 faces.

This can describe all of the formats and their rotational variants: H-cross, V-cross, 3x2, 2x3, 1x6, 6x1.

nvwarpFaceID_t

typedef enum nvwarpFaceID_t nvwarpFaceID_t

This ID is used to identify both the look-at direction and the up direction for each face.

Function Documentation

nvwarpIntoCubemap()

nvwarpResult nvwarpIntoCubemap	(	nvwarpHandle	han,
		cudaStream_t	stream,
		cudaTextureObject_t	srcTex,
		const nvwarpFaceDescription_t	faceDesc[6],
		unsigned	faceDim,
		int	interpolateEdges,
		void *	dstAddr,
		size_t	dstRowBytes
	)

Generate a cube map.

Parameters

[in]	han	The Warp360 instance. This should be initialized properly for the source and warp type (typically NVWARP_EQUIRECT_PERSPECTIVE, but NVWARP_FISHEYE_PERSPECTIVE can be used for a 360 fisheye).
[in,out]	stream	The CUDA stream on which the rendering is to be performed, or 0 for the default stream.
[in,out]	srcTex	The source texture, appropriately initialized and buffered. Clamp the edges if the source wraps around.
[in,out]	faceDesc	An array of six descriptors for each face.
[in,out]	faceDim	The dimension, in linear pixels, for each face, which will be (faceDim X faceDim).
[in,out]	interpolateEdges	If 1, the cube map will interpolate the edges; this necessarily duplicates the pixels on adjacent faces. If 0, the pixels will be sampled a half pixel away from the edges, a more uniform distribution. Greater values will extrapolate beyond the edges by half pixels; this can be useful for motion estimation.
[in,out]	dstAddr	A pointer to pixel (0,0) in the destination CUDA buffer.
[in,out]	dstRowBytes	The byte stride between pixels vertically in the destination CUDA buffer.

Returns

NVWARP_SUCCESS if successful.
