public GLRenderableBase()
prerender
public void prerender(RenderList list)
- Prepare for rendering, and potentially add itself to a list to be drawn
by a GLRenderer.
- Specified by:
prerender
in interface GLRenderable
render
public abstract void render(GLRenderer renderer,
int flags)
- Render this object using Open GL via the JOGL.
- Specified by:
render
in interface GLRenderable
- Parameters:
renderer
- renderer object which is used to perform the rendering. Provides pointers
to GL and GLU, along with helper functions.flags
- supplies flags that may be used to control different
aspects of the rendering. Flags are defined in GLRenderer
and currently include
GLRenderer.SELECTED
,
GLRenderer.VERTEX_COLORING
,
GLRenderer.HSV_COLOR_INTERPOLATION
,
GLRenderer.SORT_FACES
, and
GLRenderer.CLEAR_MESH_DISPLAY_LISTS
.
updateBounds
public void updateBounds(Point3d pmin,
Point3d pmax)
- Update the minimum and maximum points for this object. In an x-y-z
coordinate system with x directed to the right and y directed upwards, the
minimum and maximum points can be thought of as defining the
left-lower-far and right-upper-near corners of a bounding cube. This
method should only reduce the elements of the minimum point and increase
the elements of the maximum point, since it may be used as part of an
iteration to determine the bounding cube for several different objects.
- Specified by:
updateBounds
in interface GLRenderable
- Parameters:
pmin
- minimum pointpmax
- maximum point
getRenderHints
public int getRenderHints()
- Returns a bit code giving rendering hints about this renderable. Current
bit codes include
TRANSLUCENT
.
- Specified by:
getRenderHints
in interface GLRenderable
- Returns:
- bit code of rendering hints.
