The initialization structure for the built-in opengl rendering engine.
Link against: libdiguy_graphics_ogl
| int bdiGraphicsInitOgl::use_textures |
Determines whether textures will be applied.
Default is 1.
| int bdiGraphicsInitOgl::use_materials |
Determines whether materials will be applied.
Default is 1.
| GLenum bdiGraphicsInitOgl::texture_mag_filter |
Determines the OpenGL magnification filtering method for textures.
Should be one of:
Default is GL_LINEAR
| GLenum bdiGraphicsInitOgl::texture_min_filter |
Determines the OpenGL minification filtering method for textures.
Should be one of:
Default is GL_LINEAR_MIPMAP_LINEAR
| float bdiGraphicsInitOgl::texture_anisotropic_filter |
Determines the OpenGL anisotropic filtering level for textures.
Should be a power of 2 typically up to 16. Default is 0.0f
| int bdiGraphicsInitOgl::use_FBOs |
Determines whether frame buffer object extensions are used.
In some cases using frame buffer objects can improve performance of intersection testing.
This currently only has an effect on Win32 platforms.
There is a known problem with some graphics cards that using frame buffer objects leads to a program crash.
Possible values are:
| 0 | don't use frame buffer object extensions |
| 1 | do use frame buffer object extensions |
Default is 0.
| float bdiGraphicsInitOgl::polygon_offset_factor |
Sets the value passed to the factor argument of the glPolygonOffset() function.
This function is used when rendering polygon subfaces, which are commonly used for edge highlighting and decals on signs.
Default is -1.0.
| float bdiGraphicsInitOgl::polygon_offset_units |
Sets the value passed to the units argument of the glPolygonOffset() function.
Default is -1.0.
| int bdiGraphicsInitOgl::use_default_fire_weapon_intersection_function |
Sets if a default shooting intersection function should be automatically set up.
See diguyScenario::set_default_fire_weapon_intersection_function() for more details.
Default is 1.
| int bdiGraphicsInitOgl::use_cached_optimized_geometry |
Sets whether .flt and .dae files will be loaded as geometry files optimized for DI-Guy use.
Generated files will be put into a subdirectory of the DI-Guy geometry directory, and will be automatically updated as needed (doesn't exist, or original file is newer).
The .bdg geometry format is a smaller, more efficient version of the geometry data encoded in .flt and .dae files. It is an internal DI-Guy format that is not directly supported by geometry editing programs.
There is no quality trade-off in using optimized geometry files, so it is recommended that they always be enabled.
Default is 1.
| int bdiGraphicsInitOgl::use_cached_compressed_textures |
Sets whether compressed texture files should be generated from source uncompressed texture files in order to reduce texture memory usage.
There is a quality trade-off when using compressed textures. If there are too many undesired artifacts in the generated textures, they should not be used.
Generated files will be put into a subdirectory of the DI-Guy geometry directory, and will be automatically updated as needed (doesn't exist, or original file is newer).
The compressed texture files will be in the .dds (DirectDraw Surface) format.
Default is 1.
| int bdiGraphicsInitOgl::use_sRGB_corrected_textures |
Sets whether SRGB textures should be used, these allow a relatively free lookup into texture maps that have been transformed into sRBG space allowing a linear lighting pipeline to be setup.
Default is 1.
| int bdiGraphicsInitOgl::use_4x3_shader_matrices |
Whether matrices that will be used as transforms in shaders should be sent as a 4x3 matrix instead of 4x4.
This should only be changed if your video card is unable to use 4x4 matrices.
Default is 1.
| int bdiGraphicsInitOgl::use_shader_instancing |
Whether instancing should be used for rendering.
Default is 0.
| int bdiGraphicsInitOgl::instancing_respect_graphics_state_switch |
Instructs the instancing system to respect the graphics state switch of geometry when constructing instance groups.
Setting value to 0 while not graphically correct results in increased performance
Default is 1.
| int bdiGraphicsInitOgl::use_qt_license_dialog |
Instructs the initializing system to pop up a Qt based dialog box for setting up licensing.
Default is 1.
1.8.9.1
