Madguy on January 26, , pm. As MadGuy said these artifact are down to transparency and backface being enabled at the same time. This requires changing of the backface culling in the rendering pipeline in some manner. This in general means handle the rendering at a much lower level than a scene veiwer, though GLScene does have a GLDirectOpenGL item for such occasions, As to the detail of your issue perhaps you could get some pointers from Sourceforge where the GLScene devs hang out.
The easiest alternative would be to create a thin box or plate and turn face culling back on. You would probably have to make your own if you wanted to skin it with your choice of uv texture mapping.
If you want to continue using transparent objects, you have two options only: 1 Raytracing. Slow and it's performance drops exponentially with increase of scene complexity.
Isn't suitable for real time graphics. Such engines were used for software rendering in old games, like Quake and Half-Life. Triangles are properly sorted, when using such engine, and therefore transparency is automatically supported right out of box. CSG is usually also supported right out of box, cuz it's needed by engine itself to handle overlapping objects. Bye, Pepecito. Reimar Grabowski wrote some opengl bindings for linux, I wrote a gtkglarea control, which is a opengl control for the LCL.
There is also an example. This is somewhat linux specific at the moment, but maybe a start. See also the asmoday project on sourceforge. EricGrange New Member Posts: Marc Administrator Hero Member Posts: Quote from: "EricGrange". Use the bug tracker.
Anonymous Guest. This means that when the control gets updated, it is first painted in gray, then painted by OpenGL, which results in very visible flickering. Maybe there is another way to achieve that in LCL?
ScanLines is just an access to the bitmap as a raster, and unless bitmaps have been assimilated to graphic objects, icons or glyphs in LCL, bitmaps are supposed to be The Newton-GLScene binding based on Tag and User Data previously described will be very usefull here, since you will be able to write UpdateGraphicObject callback in a generic way, retrieving the graphical object to be updated from the body passed to it.
Several of the sources of help are for old versions of GLScene and for Delphi rather than Lazarus, but can still be useful if you make allowances for differences such as changed package names. This page regroups the most frequently asked questions and their answers.
If you right click them again, you can now update them whenever you want. Similarly we need to update the position of the GLCube in the Glworld when the postion of our body in de newton world changes.
The scribd tutorial entitled Build a basic scene provides clear instructions for Delphi supported by many screenshots. Finally the DummyCube is also commonly used as Camera Target with the Camera a child of its target dummy cube or vice-versa. First, install the package, new components will be added to your palette. Wiki A wiki at http: The very first objects you will probably want to add are a Camera, gutorial Light and an object f. Assuming the Centre of Gravity is located at the Centre of the body we can use:.
