fetch_sample()

template<typename VDB_attrib_type , VDB_volume_filter_mode VDB_filter_mode, typename VDB_grid_type , bool VDB_sampler_use_cache>

VDB_attrib_type nv::index::xac::VDB_sampler< VDB_attrib_type, VDB_filter_mode, VDB_grid_type, VDB_sampler_use_cache >::fetch_sample

(

const float3 &

sample_position

)

const

Sample a VDB volume attribute at the provided sample location.

This method always returns a filtered volume sample without classifying it using a colormap.

Parameters

[in]

sample_position

Sample position defined in volume local/object space.

Returns

Filtered volume sample according to the selected volume filter mode.

fetch_sample_classify()

template<typename VDB_attrib_type , VDB_volume_filter_mode VDB_filter_mode, typename VDB_grid_type , bool VDB_sampler_use_cache>

float4 nv::index::xac::VDB_sampler< VDB_attrib_type, VDB_filter_mode, VDB_grid_type, VDB_sampler_use_cache >::fetch_sample_classify	(	const float3 &	sample_position,
		const xac::Colormap &	color_map
	)		const

Sample a VDB volume attribute at the provided sample location.

This method always returns a filtered and classified volume sample using the provided colormap.

Parameters

[in]	sample_position	Sample position defined in volume local/object space.
[in]	color_map	Colormap for classification of volume sample.

Returns

Filtered and classified volume sample according to the selected volume filter mode and volume classification mode.
