Description
This extension allows to generate grass on the top of meshes. It works as a object modifier plugin. Internally it creates blades and converts them to different grass primitives depending on the user parameters.
Example of how to create a MaxwellGrass object:
// If we don't need to call functions such as CgeometryModifierExtension::getProxyDisplayPoints() // (i.e for display purposes) // then it is possible to define procedural geometries or object modifiers // without loading extension dynamic libraries (.mxx files) // but a MXparamList object can be created and filled with the desired parameters. Cmaxwell::Cobject mesh = pMaxwell->createMesh( ... ); // ...fill mesh parameters MXparamList* grassParams = new MXparamList( "MaxwellGrass" ); float bladesDensity = 500.0; grassParams->setFloat( "Density", bladesDensity ); float length = 0.25; grassParams->setFloat( "Length ", length ); grassParams->setString( "Material", materialName ); //...etc.. object.applyGeometryModifierExtension( grassParams );
