OpenGL: 3D Extensions

Postby Technologov » 20. Dec 2008, 12:01

Hi All !

As you may know, VirtualBox 2.1.0 is a very major leap forward, because it is the first release to support 3D Acceleration in form of OpenGL on Windows XP & Vista guests !

Here is a comparison of the OpenGL extensions supported by VirtualBox as compared to my host: (ATI Radeon HD 3850)

Guest: (Windows XP, Virtual Box 2.1.0)

ARB:
GL_ARB_depth_texture
GL_ARB_fragment_program
GL_ARB_multisample
GL_ARB_multitexture
GL_ARB_occlusion_query
GL_ARB_point_parameters
GL_ARB_point_sprite
GL_ARB_shadow
GL_ARB_shadow_ambient
GL_ARB_texture_border_clamp
GL_ARB_texture_compression
GL_ARB_texture_cube_map
GL_ARB_texture_env_add
GL_ARB_texture_env_combine
GL_ARB_texture_env_crossbar
GL_ARB_texture_env_dot3
GL_ARB_transpose_matrix
GL_ARB_vertex_buffer_object
GL_ARB_vertex_program
GL_ARB_window_pos

GL_EXT_blend_color
GL_EXT_blend_minmax
GL_EXT_blend_func_separate
GL_EXT_blend_subtract
GL_EXT_texture_env_add
GL_EXT_texture_env_dot3
GL_EXT_texture_env_combine
GL_EXT_fog_coord
GL_EXT_multi_draw_arrays
GL_EXT_secondary_color
GL_EXT_shadow_funcs
GL_EXT_stencil_wrap
GL_EXT_texture_cube_map
GL_EXT_texture_edge_clamp
GL_EXT_texture_filter_anisotropic
GL_EXT_texture_lod_bias
GL_EXT_texture_object
GL_EXT_texture3D
GL_EXT_texture_rectangle

GL_NV_texgen_reflection

GL_SGIS_generate_mipmap
GL_SGIS_texture_edge_clamp

GL_CR_state_parameter
GL_CR_cursor_position
GL_CR_bounding_box
GL_CR_print_string
GL_CR_tilesort_info
GL_CR_synchronization
GL_CR_head_spu_name
GL_CR_performance_info
GL_CR_window_size
GL_CR_tile_info
GL_CR_saveframe
GL_CR_readback_barrier_size
GL_CR_server_id_sharing
GL_CR_server_matrix

Basically guest sees 58 OpenGL extensions out of 97 available on the host.

WGL_ARB_make_current_read
WGL_EXT_extensions_string
WGL_ARB_buffer_region
WGL_EXT_framebuffer_sRGB
WGL_ATI_render_texture_rectangle

The host has all 97 extensions.

Another problem: Even the most basic OpenGL test made my XP guest stuck. I had to reboot the VM.

I used OpenGL Extensions Viewer v2.05 from:
www.realtech-vr.com

The basic test that got stuck my VM is also the same "OpenGL Extensions Viewer".

I hope VirtualBox developers will find my report useful.
