Constructor & Destructor Documentation

mi::shader_v3::Access_bsdf::Access_bsdf ( miState * state ) [inline]

Accesses a Bsdf.
The created access will attempt to acquire a Bsdf instance from a pool by executing the shader that is attached to the bsdf slot in the current material. The access is valid if the bsdf slot is populated with a valid BSDF wrapper shader.

Parameters:

state the current state

mi::shader_v3::Access_bsdf::Access_bsdf ( ) [inline]

Creates an invalid Bsdf access.
The Access_bsdf::reset function must be called before this access can be used.

mi::shader_v3::Access_bsdf::~Access_bsdf ( ) [inline]

Destroys the access.
All acquired resources are released.

Member Function Documentation

void mi::shader_v3::Access_bsdf::reset ( miState * state = 0 ) [inline]

Resets this access to a new Bsdf.
This function allows manual control over the lifetime of the accessed Bsdf. If state is 0 (the default), the Bsdf instance will be released.

bool mi::shader_v3::Access_bsdf::valid ( ) const [inline]

Checks if the access is valid.

Returns:
true if a Bsdf instance was found on construction, false otherwise.
