static GU_ConstDetailHandle GU_Interpolate::fastInterpolate ( const DetailList geo,
const fpreal weights 
)
static

Perform a weighted sum of the geometry. sum(weights) should be 1.

This method assumes topology on all the geometry matches. Attributes don't have to match, but the primitive types and topology do.

static GU_ConstDetailHandle GU_Interpolate::fastLerp ( const GU_ConstDetailHandle g0,
const GU_ConstDetailHandle g1,
fpreal  t 
)
static

Linear interpolate between two pieces of geometry. t should be between 0 and 1.

This method assumes the topology matches. Attributes don't have to match, but the primitive types and topology do.

static GU_ConstDetailHandle GU_Interpolate::interpolate ( const DetailList geo,
const fpreal weights 
)
static

Perform a weighted sum of the geometry. sum(weights) should be 1.

This method verifies the topology of the geometry matches before performing interpolation. All geometry which matches topology with the input with the largest weight will be considered. Any geometry which doesn't match will have its weight distributed amongst the other geometry.

static GU_ConstDetailHandle GU_Interpolate::lerp ( const GU_ConstDetailHandle g0,
const GU_ConstDetailHandle g1,
fpreal  t 
)
static

Linear interpolate between two pieces of geometry. t should be between 0 and 1.

This method verifies the topology of the two details matches before performing interpolation. If the topology doesn't match, the method returns the geometry with the largest contribution.

static bool GU_Interpolate::matchTopology ( const GU_ConstDetailHandle g0,
const GU_ConstDetailHandle g1 
)
static

Check to see whether geometry matches topology and can be interpolated. This doesn't verify that the attributes for geometries match, only the topology.

static bool GU_Interpolate::matchTopology ( const GU_Detail g0,
const GU_Detail g1 
)
static

Check to see whether geometry matches topology and can be interpolated. This doesn't verify that the attributes for geometries match, only the topology.
