display_scene_3d — Display a 3D scene.
display_scene_3d( : : WindowHandle, Scene3D, CameraIndex : )
display_scene_3d displays the 3D scene Scene3D in the window WindowHandle. The view of the camera CameraIndex is used to render the scene. See create_scene_3d for a short example.
display_scene_3d requires OpenGL 2.1, GLSL 1.2, and the OpenGL extensions GL_EXT_framebuffer_object and GL_EXT_framebuffer_blit. Otherwise the compatibility mode with less requirements but lower quality is automatically enabled. On graphics cards with low memory the following error messages could occur if rendering in a window with high resolution:
Low level error: 'Incomplete attachment'
Unhandled Exception: 'Required framebuffer object is unsupported'
Solutions:
Set the parameter 'quality' to 'low' using set_scene_3d_param or use the compatibility mode to reduce the requirements of the graphics card.
The system variable (see set_system) 'opengl_compatibility_mode_enable' can be set to 'true' to permanently enable the visualisation in compatibility mode with lower OpenGL requirements. This mode requires OpenGL 1.1. In compatibility mode the parameters 'object_index_persistence', 'depth_persistence' and 'quality' are not used.
On Linux Remote Desktop 'disp_background' is not supported.
Window handle.
Handle of the 3D scene.
Index of the camera used to display the scene.
display_scene_3d returns 2 (H_MSG_TRUE) if all parameters are correct. If necessary, an exception is raised.
