Detailed Description

This effect makes surfaces appear bumpy. Children nodes must use two textures, one for diffuse color and one for the normal map (which can be created from a height map with tools like nVIDIA's normal map generator). Furthermore, tangent-space basis vectors must be created and assigned to each Geometry; this can be done quickly by calling BumpMapping::prepareChildren(). Note that both diffuse and normal map textures must have corresponding UV maps defined in Geometry objects. This effect defines a preferred technique which uses ARB vertex & fragment programs, and a fallback technique which doesn't use fragment programs. The latter is more limited though since it can't handle ambient and specular components.

Member Function Documentation

◆ define_techniques()

bool osgFX::BumpMapping::define_techniques ( )
protectedvirtual

abstract method to be implemented in derived classes; its purpose if to create the techniques that can be used for obtaining the desired effect. You will usually call addTechnique() inside this method.

Implements osgFX::Effect.

◆ getDiffuseTextureUnit()

int osgFX::BumpMapping::getDiffuseTextureUnit ( ) const
inline

get the texture unit that contains diffuse color texture. Default is 1

◆ getLightNumber()

int osgFX::BumpMapping::getLightNumber ( ) const
inline

get the OpenGL light number

◆ getNormalMapTextureUnit()

int osgFX::BumpMapping::getNormalMapTextureUnit ( ) const
inline

get the texture unit that contains normal map texture. Default is 0

◆ getOverrideDiffuseTexture() [1/2]

osg::Texture2D * osgFX::BumpMapping::getOverrideDiffuseTexture ( )
inline

get the diffuse color texture that overrides children's texture

◆ getOverrideDiffuseTexture() [2/2]

const osg::Texture2D * osgFX::BumpMapping::getOverrideDiffuseTexture ( ) const
