int ON_Material::AddTexture | ( | const ON_Texture & | tx | ) |
Description: If there is already a texture with the same file name and type, then that texture is modified, otherwise a new texture is added. If tx has user data, the user data is copied to the m_textures[] element. Parameters: tx - [in] Returns: Index of the added texture in the m_textures[] array. Remarks: This is intended to be a quick and simple way to add textures to the material. If you need to do something different, then just work on the m_textures[] array.
int ON_Material::AddTexture | ( | const wchar_t * | filename, |
ON_Texture::TYPE | type | ||
) |
Description: If there is a texture with a matching type, that texture's filename is modified, otherwise a new texture is added. Parameters: filename - [in] new filename type - [in] Returns: Index of the added texture in the m_textures[] array. Remarks: This is intended to be a quick and simple way to add textures to the material. If you need to do something different, then just work on the m_textures[] array.

int ON_Material::DeleteTexture | ( | const wchar_t * | filename, |

Description: Deletes all textures with matching filenames and types. Parameters: filename - [in] If nullptr, then any filename matches. type - [in] If ON_Texture::no_texture_type, then any texture type matches. Returns: Number of textures deleted.
ON_Color ON_Material::Diffuse | ( | ) | const |
bool ON_Material::DisableLighting | ( | ) | const |
Returns: True if lighting is disabled. Remarks: True means render this object without applying any modulation based on lights. Basically, the diffuse, ambient, specular and emissive channels get combined additively, clamped, and then get treated as an emissive channel. Another way to think about it is when m_bDisableLighting is true, render the same way OpenGL does when ::glDisable( GL_LIGHTING ) is called.

int ON_Material::FindTexture | ( | const wchar_t * | filename, |
ON_Texture::TYPE | type, | ||
int | i0 = -1 |
||
) | const |
Description: Searches for a texture with matching filename and type. If more than one texture matches, the first match is returned. Parameters: filename - [in] If nullptr, then any filename matches. type - [in] If ON_Texture::no_texture_type, then any texture type matches. i0 - [in] If i0 is < 0, the search begins at m_textures[0], if i0 >= m_textures.Count(), -1 is returned, otherwise, the search begins at m_textures[i0+1]. Example: Iterate through all the the bitmap textures on a material.
ON_Material& mat = ...; int ti = -1; int bitmap_texture_count = 0; for(;;) { ti = mat.FindTexture( nullptr, ON_Texture::TYPE::bitmap_texture, ti ); if ( ti < 0 ) {
/ no more bitmap textures break; }
/ we have a bitmap texture bitmap_texture_count++; const ON_Texture& bitmap_texture = mat.m_textures[ti]; ... }
Returns: >=0 m_textures[] index of matching texture -1 if no match is found.
int ON_Material::FindTexture | ( | ON_UUID | texture_id | ) | const |
Description: Searches for a texture with matching texture_id. If more than one texture matches, the first match is returned. Parameters: texture_id - [in] Returns: >=0 m_textures[] index of matching texture -1 if no match is found.

Parameters: fresnel_index_of_refraction - [in] ON_Material::Material::Default.m_fresnel_index_of_refraction is a good default N - [in] 3d surface normal R - [in] 3d reflection direction Returns: 1.0: The input values were not valid or the calculation failed due to a divide by zero or some other numerical arithmetic failure. fresnel reflection coefficient 1/2 * ((g-c)/(g+c))^2 * (1 + ( (c*(g+c) -1)/(c*(g+c) + 1) )^2) where c = N o (N-R); ///< c = 3d vector dot product of N and (N-R) and g = sqrt(fresnel_index_of_refraction*fresnel_index_of_refraction + c*c - 1.0).
double ON_Material::FresnelReflectionCoefficient | ( | ON_3dVector | N, |
ON_3dVector | R | ||
) | const |
Parameters: N - [in] 3d surface normal R - [in] 3d reflection direction Returns: If m_bFresnelReflections is false, then 1.0 is returned. If m_bFresnelReflections is true, then the value of the fresnel reflection coefficient is returned. In typical rendering applications, the reflection term is multiplied by the fresnel reflection coefficient before it is added to the diffuse color. If any input is not valid or the calculation fails, then 1.0 is returned. Remarks: When m_bFresnelReflections is true, the calculation is performed by calling ON_FresnelReflectionCoefficient() with m_fresnel_index_of_refraction as the fresnel index of refraction.
bool ON_Material::FresnelReflections | ( | ) | const |
Reflection and Refraction settings The bool m_bFresnelReflections enables fresnel scaling of reflection contributions to the diffuse color. True: The fresnel term is used to scale the reflection contribution before addition to the diffuse component. False: The reflection contribution is simply added to the diffuse component.
|
static |
Parameters: model_component_reference - [in] none_return_value - [in] value to return if ON_Material::Cast(model_component_ref.ModelComponent()) is nullptr Returns: If ON_Material::Cast(model_component_ref.ModelComponent()) is not nullptr, that pointer is returned. Otherwise, none_return_value is returned.
bool ON_Material::IsPhysicallyBased | ( | void | ) | const |
Call this function to determine if the material should be treated as Physically Based (ie - a PBR material) If this function returns true, the call to PhysicallyBased will return a non-null pointer. If the function returns false, use the legacy interface (Diffuse etc). Conversion of a non-PBR material to PBR is possible by calling ConvertToPhysicallyBased.

const ON_UUID ON_Material::MaterialChannelIdFromIndex | ( | int | material_channel_index | ) | const |
Parameters: material_channel_index - [in]
Returns: If material_channel_index > 0, the m_id ON_UUID value of the first element in the m_material_channel[] array with material_channel_index = ON_Uuid_index.m_i is returned. This id identifies an ON_Material. Otherwise ON_nil_uuid is returned.
int ON_Material::MaterialChannelIndexFromId | ( | ON_UUID | material_channel_id | ) | const |
Parameters: material_channel_id - [in] Returns: If material_channel_id is not nil, the m_i index value of the first element in the m_material_channel[] array with material_channel_id = ON_Uuid_index.m_id is returned. Otherwise 0 is returned.
int ON_Material::MaterialChannelIndexFromId | ( | ON_UUID | material_channel_id, |
bool | bAddIdIfNotPresent | ||
) |
Parameters: material_channel_id - [in] bAddIdIfNotPresent - [in] Returns: If material_channel_id is not nil, the m_i index value of the first element in the m_material_channel[] array with material_channel_id = ON_Uuid_index.m_id is returned. If material_channel_id is not nil an no element of the m_material_channel[] array has a matching id, a new element is added with a unique channel index > 0 and that index is returned. Otherwise 0 is returned.
ON_UUID ON_Material::MaterialPlugInId | ( | ) | const |

Convert a legacy material to a PBR material that is the best approximation of the original. After calling this function, the material is guaranteed to return true to material.IsPhysicallyBased()
double ON_Material::Transparency | ( | ) | const |
Transparency values are in range 0.0 = opaque to 1.0 = transparent.
bool ON_Material::UseDiffuseTextureAlphaForObjectTransparencyTexture | ( | ) | const |
If m_bUseDiffuseTextureAlphaForObjectTransparencyTexture is true, the alpha channel of the texture in m_textures with m_type=bitmap_texture is used in addition to any textures with m_type=transparency_texture.

Description: Low level archive writing tool used by ON_BinaryArchive::WriteObject(). Parameters: binary_archive - archive to write to Returns: Returns true if the write is successful. Remarks: Use ON_BinaryArchive::WriteObject() to write objects. This Write() function should just write the specific definition of this object. It should not write and any chunk typecode or length information.
The default implementation of this virtual function returns false and does nothing.
Reimplemented from ON_Object.

double ON_Material::m_fresnel_index_of_refraction = 1.56 |
m_fresnel_index_of_refraction: Default is 1.56. This is the value ON:Material::FresnelReflectionCoefficient() passes as the first parameter to ON_FresnelReflectionCoefficient().
double ON_Material::m_index_of_refraction = 1.0 |
m_index_of_refraction: Default is 1.0. Physically, the index of refraction is >= 1.0 and is the value (speed of light in vacuum)/(speed of light in material). Some rendering algorithms set m_index_of_refraction to zero or values < 1.0 to generate desirable effects.
ON_SimpleArray<ON_UuidIndex> ON_Material::m_material_channel |
Description: The m_material_channel[] array is used to provide per face rendering material support for ON_SubD and ON_Brep objects. ON_Mesh objects to not support per face render materials. The application specifies a base ON_Material for rendering the subd or brep and a way to find materials from ON_UUID values. ON_Material.Id() returns the id for any given material.
ON_BrepFace::MaterialChannelIndex() and ON_SubDFace::MaterialChannelIndex() specify a material channel index. If this value is 0, then the base material is used to render the face. Otherwise the material with id = base.MaterialChannelIdFromIndex( face.MaterialChannelIndex() ) is used to render the face.
