Function Documentation

int OivInstanceID

(

)

Get the current instance ID when using multiple instance.

Returns:

the shape instance ID.

mat4 OivInstanceMatrix

(

)

Get the transformation matrix to apply to the current geometry instance, i.e., the combination of instance rotation, scale and translation.

Returns:

the shape instance transformation matrix.

vec4 OivInstanceRotation

(

)

Get the rotation (i.e.

a quaternion) to apply to the current geometry instance.

Returns:

the shape instance rotation

vec3 OivInstanceScale

(

)

Get the scale vector to apply to the current geometry instance.

Returns:

the shape instance scale.

vec3 OivInstanceTranslation

(

)

Get the translation vector to apply to the current geometry instance.

Returns:

the shape instance translation.

void OivInstancingInit

(

)

Initialize instancing.

Must be called when doing instancing.
