Member Enumeration Documentation

◆ FilterType

enum ANSYS::Nexus::GLTFWriter::Sampler::FilterType

Describes how the texel color is calculated from the texture map given the texture coordinates.

Enumerator
FT_NEAREST 

Choose nearest texel.

FT_LINEAR 

Linearly interpolate between the two nearest texels.

FT_NEAREST_MIPMAP_NEAREST 

Choose nearest texel in nearest mipmap.

FT_LINEAR_MIPMAP_NEAREST 

Linearly interpolate between the two nearest texels of the nearest mipmap.

FT_NEAREST_MIPMAP_LINEAR 

Choose nearest texel in linearly interpolated mipmap between two nearest mipmaps.

FT_LINEAR_MIPMAP_LINEAR 

Linearly interpolate between the two nearest texels in the linearly interpolated mipmap between two nearest mipmaps.

Definition at line 29 of file GLTFSampler.h.

◆ WrapType

enum ANSYS::Nexus::GLTFWriter::Sampler::WrapType

Describes how texture coordinates wrap.

Enumerator
WT_REPEAT 

Fractional value of texture coordinate is used.

WT_CLAMP_TO_EDGE 

0 is used for texture coordinates < 0 and 1 is used for texture coordinates > 1.

WT_MIRRORED_REPEAT 

fractional value of texture coordinate is used, but value alternates going from 0 to 1 and [1 - (0 to 1)]

Member Function Documentation

◆ Create()

static Sampler* ANSYS::Nexus::GLTFWriter::Sampler::Create ( GLTF *  gltf,
FilterType  minFilter,
FilterType  magFilter,
WrapType  wrapS,
WrapType  wrapT 
)
static

Creates a sampler.

Returns
Sampler object. Do not delete this pointer.
Parameters
[in]gltfGLTF object.
[in]minFilterSampler::FilterType describing how the texel color is calculated from the texture map given the texture coordinates. A minFilter is used when the texture coordinate covers an area larger than a texture texel.
[in]magFilterSampler::FilterType describing how the texel color is calculated from the texture map given the texture coordinates. A magFilter is used when the texture coordinate covers an area smaller than a texture texel. Possible values are:
  • FT_NEAREST
  • FT_LINEAR
[in]wrapSSampler::WrapType describing how texture coordinates wrap. This is the S texture coordinate (like X). Textures are always accessed with values that range from 0 to 1. This describes how texture coordinates outside this range are handled.
[in]wrapTSampler::WrapType see wrapS. This is the T texture coordinate (like Y).
