get()

template<class T = f32x4>

T get ( uint3 position, uint8 mip ) const

inlinenoexcept

Returns texel at specified position and mip level.

Parameters

position	texel 3D position and mipmap level
mip	texture mipmap level (default = 0)

Template Parameters

T	type of the texture pixel

sampleNearest()

template<class T = f32x4>

T sampleNearest ( float3 uv, float mip, bool repeatMode = false ) const

inlinenoexcept

Samples nearest texel from an image.

Parameters

uv	3D texture coordinates where to sample
mip	mipmap level to sample (default = 0.0)
repeatMode	clamp to border or repeat sampling mode

Template Parameters

T	type of the texture pixel
