Method Detail

fromGSceneToGLScene

public static GLScene fromGSceneToGLScene(GScene gscene)

Translates a GScene into a GLScene

fromGMeshToGLBasicMesh

public static GLBasicMesh fromGMeshToGLBasicMesh(GMesh gmesh)

Creates a new GLBasicMesh, from data obtained from the specified GMesh. The GMesh type should be either Triangles or PolyList. In the latter case, the GMesh will be triangulated first. The GMesh should include indices; they will be unified into a shared index for all attributes, if necessary. Note that triangulation and index unification have side effects on the GMesh parameter.

fromGSkinnedMeshToGLSkinnedMesh

public static GLSkinnedMesh fromGSkinnedMeshToGLSkinnedMesh(GSkinnedMesh gmesh)

addGLBasicMeshAttributes

private static void addGLBasicMeshAttributes(GMesh gmesh,
                                             GLBasicMesh glmesh)

fromGShapeToGLShape

public static GLShape fromGShapeToGLShape(GShape gshape,
                                          List<GLSkinnedMesh> glSkinnedMeshes)

Translates a scenegraph GShape into an opengl GLShape

fromGNodeToVJoint

public static VJoint fromGNodeToVJoint(GNode gnode,
                                       GLRenderList glShapeList,
                                       List<GLSkinnedMesh> glSkinnedMeshes)

Translates a GNode base scenegraph into a VJoint based scenegraph plus a list of GLShape RenderObjects. The latter are linked to the VJoints, via their transform matrices. The root VJoint is returned. The GLRenderObjects are added to a shapeList.
