rpr_curve_parameter

Usage

Information on rpr_curve objects, corresponds to rprContextCreateCurve parameters.

Possible Values

Name	Value	Brief Explanation
RPR_CURVE_CONTROLPOINTS_COUNT	0x830	Number of control points.
RPR_CURVE_CONTROLPOINTS_DATA	0x831	Control point list. Each curve is made of a list of points, an rpr_curve object can have multiple curves of num_segments each, each segment is 4 control points.
RPR_CURVE_CONTROLPOINTS_STRIDE	0x832	Bytes in each control point.
RPR_CURVE_INDICES_COUNT	0x833	Number of indices.
RPR_CURVE_INDICES_DATA	0x834	List of indices. Curves can share control points and reference them by indices.
RPR_CURVE_RADIUS	0x835	Radius of curves. All curves in an rpr_curve object have one radius.
RPR_CURVE_UV	0x836	UV coordinates. One per curve in an rpr_curve object. Useful for texturing color per curve.
RPR_CURVE_COUNT_CURVE	0x837	Number of curves or hairs.
RPR_CURVE_SEGMENTS_PER_CURVE	0x838	Segments per curve. 4 points per segment.
RPR_CURVE_CREATION_FLAG	0x839	Creation flag set on the curve. Currently, this is 0 or 1 if a curve is tapered.
RPR_CURVE_NAME	RPR_OBJECT_NAME	Custom name set with rprObjectSetName().
RPR_CURVE_UNIQUE_ID	RPR_OBJECT_UNIQUE_ID	ID for this object.
RPR_CURVE_CUSTOM_PTR	RPR_OBJECT_CUSTOM_PTR	Custom pointer, if set on this object.
RPR_CURVE_TRANSFORM	RPR_SHAPE_TRANSFORM	Tranform (16 float values) for the curve.
RPR_CURVE_MATERIAL	RPR_SHAPE_MATERIAL	Pointer to the material set on the curve.
RPR_CURVE_VISIBILITY_PRIMARY_ONLY_FLAG	RPR_SHAPE_VISIBILITY_PRIMARY_ONLY_FLAG	Copy from shape value flags.
RPR_CURVE_VISIBILITY_SHADOW	RPR_SHAPE_VISIBILITY_SHADOW	Visibility to shadow rays.
RPR_CURVE_VISIBILITY_REFLECTION	RPR_SHAPE_VISIBILITY_REFLECTION	Visibility to reflection rays.
RPR_CURVE_VISIBILITY_REFRACTION	RPR_SHAPE_VISIBILITY_REFRACTION	Visibility to refraction rays.
RPR_CURVE_VISIBILITY_TRANSPARENT	RPR_SHAPE_VISIBILITY_TRANSPARENT	Visibility to transparent objects.
RPR_CURVE_VISIBILITY_DIFFUSE	RPR_SHAPE_VISIBILITY_DIFFUSE	Visibility to diffuse rays.
RPR_CURVE_VISIBILITY_GLOSSY_REFLECTION	RPR_SHAPE_VISIBILITY_GLOSSY_REFLECTION	Visibility to glossy reflection rays.
RPR_CURVE_VISIBILITY_GLOSSY_REFRACTION	RPR_SHAPE_VISIBILITY_GLOSSY_REFRACTION	Visibility to glossy refraction rays.
RPR_CURVE_VISIBILITY_LIGHT	RPR_SHAPE_VISIBILITY_LIGHT	Visibility to lights.
