Detailed Description

Single channel of a Houdini DSM image.

A Houdini deep shadow/camera file can have any number of image channels (planes). A DSM image contains a single channel for opacity. A deep camera image has the opacity channel along with any number of extra image channels.

Constructor & Destructor Documentation

IMG_DeepShadowChannel::IMG_DeepShadowChannel	(	const char *	name,
		int	float_offset,
		int	tuple_size,
		const char *	storage = "real32"
	)

Parameters

name	The unique name of the DSM channel
float_offset	When data is read or written in deep shadow files, the pixel data is interleaved. That is, the data for a single pixel can be represented as an array of floats. Each channel has a unique offset into the array. The user should not assume that the offsets are contiguous. For example, the pixel data might look like: [ Of.r, // Opacity red Of.g, // Opacity green Of.b, // Opacity blue Cf.r, // Color (red) Cf.g, // Color (green) Cf.b, // Color (blue) s, // s coordinate t, // t coordinate N.x, // Normal x N.y, // Normal y N.z, // Normal z ] Where the channels would be defined by: IMG_DeepShadowChannel("Of", 0, 3); IMG_DeepShadowChannel("Cf", 3, 3); IMG_DeepShadowChannel("s", 6, 1); IMG_DeepShadowChannel("t", 7, 1); IMG_DeepShadowChannel("N", 8, 3);
tuple_size	Number of floats
storage	Storage type. This may be one of { "real16", "real32", "real64" }. This value represents the storage of the channel in the file.
