INormalShader class¶
<oceansdk/normalshaderplugin.h>
Description¶
This interface class allows calling a Normal shader
In the SDK, you will either:
- Use this class directly to call a child normal shader
- Use the derived class
INormalShaderPlugin
to create a plugin normal shader
Namespace¶
This class is in the namespace Ocean::Sdk

class
INormalShader
: public INode¶ -
Vec3<float>
valueTS
(const IShaderContext *sc) const¶ [virtual]
Returns the shaded normal vector in the original surface tangent space for the given shader context
sc
.Parameters: sc – The shading context for this shader evaluation
-
Vec3<float>
shadeWS
(const IShaderContext *sc, const Vec3<float> &normalWS) const¶ [virtual]
Transforms a given world space normal vector.
This normal shading operation is done in addition to the one performed by
shadeWS()
.It is useful for modelling normal perturbations not easy to describe using
shadeWS()
, such as slight panel tilts over a building surface.Parameters: - sc – The shading context for this shader evaluation
- normalWS – The original world space normal vector
