Detailed Description

System defaults for the most common used mesh vertex attributes. If no bindings are specified in the material, the system will automatically try to bind the vertex data of a mesh to the inputs of a shader using these names.

When CUSTOM vertex buffers are used, you have to manually bind all the mesh vertex attributes, including the default ones, to the shader inputs. Both nap::Material and nap::MaterialInstance allow you to explicitly bind vertex data to shader inputs.

Function Documentation

getColorName()

const NAPAPI std::string nap::vertexid::getColorName

(

int

colorChannel

)

Returns the name of the vertex color attribute based on the queried color channel, ie: "Color0", "Color1" etc.

Parameters

colorChannel

the color channel index

Returns

the name of the color vertex attribute

getUVName()

const NAPAPI std::string nap::vertexid::getUVName

(

int

uvChannel

)

Returns the name of the vertex uv attribute based on the queried uv channel, ie: UV0, UV1 etc.

Parameters

uvChannel

the uv channel index

Returns

the name of the vertex attribute
