Function documentation

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasSpecularTexture() const

Whether the material has a specular texture.

Returns true if any of the MaterialAttribute::SpecularTexture or MaterialAttribute::SpecularGlossinessTexture attributes is present, false otherwise.

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasGlossinessTexture() const

Whether the material has a glossiness texture.

Returns true if any of the MaterialAttribute::GlossinessTexture or MaterialAttribute::SpecularGlossinessTexture attributes is present, false otherwise.

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasSpecularGlossinessTexture() const

Whether the material has a combined specular/glossiness texture.

Returns true if either the MaterialAttribute::SpecularGlossinessTexture attribute is present or both MaterialAttribute::SpecularTexture and MaterialAttribute::GlossinessTexture are present, point to the same texture ID and MaterialAttribute::GlossinessTextureSwizzle is set to MaterialTextureSwizzle::A, and ddditionally MaterialAttribute::SpecularTextureMatrix and MaterialAttribute::GlossinessTextureMatrix are both either not present or have the same value, MaterialAttribute::SpecularTextureCoordinates and MaterialAttribute::GlossinessTextureCoordinates are both either not present or have the same value, and MaterialAttribute::SpecularTextureLayer and MaterialAttribute::GlossinessTextureLayer are both either not present or have the same value; false otherwise.

In other words, if this function returns true, specularTexture(), specularTextureMatrix(), specularTextureCoordinates() and specularTextureLayer() return values common for both specular and glossiness texture, and the two are packed together with specular occupying the RGB channels and glossiness the alpha.

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasCommonTextureTransformation() const

Whether the material has a common transformation for all textures.

Returns true if, for each texture that is present, diffuseTextureMatrix(), specularTextureMatrix(), glossinessTextureMatrix(), normalTextureMatrix(), occlusionTextureMatrix() and emissiveTextureMatrix() have the same value, false otherwise. In particular, returns true also if there's no texture transformation at all. Use hasTextureTransformation() to distinguish that case.

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasCommonTextureCoordinates() const

Whether the material has a common coordinate set for all textures.

Returns true if, for each texture that is present, diffuseTextureCoordinates(), specularTextureCoordinates(), glossinessTextureCoordinates(), normalTextureCoordinates(), occlusionTextureCoordinates() and emissiveTextureCoordinates() have the same value, false otherwise. In particular, returns true also if there's no extra texture coordinate set used at all. Use hasTextureCoordinates() to distinguish that case.

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasTextureLayer() const

Whether the material uses array texture layers.

Returns true if any of the MaterialAttribute::DiffuseTextureLayer, MaterialAttribute::SpecularTextureLayer, MaterialAttribute::GlossinessTextureLayer, MaterialAttribute::NormalTextureLayer, MaterialAttribute::OcclusionTextureLayer, MaterialAttribute::EmissiveTextureLayer or MaterialAttribute::TextureLayer attributes is present and has a non-zero value, false otherwise.

bool Magnum::Trade::PbrSpecularGlossinessMaterialData::hasCommonTextureLayer() const

Whether the material has a common array texture layer for all textures.

Returns true if, for each texture that is present, diffuseTextureLayer(), specularTextureLayer(), glossinessTextureLayer(), normalTextureLayer(), occlusionTextureLayer() and emissiveTextureLayer() have the same value, false otherwise. In particular, returns true also if there's no array texture layer used at all. Use hasTextureLayer() to distinguish that case.
