Manage environment textures for image-based lighting (IBL) The jit.gl.environment object utilizes internal jit.gl.cubemap and jit.openexr objects for loading and uploading equirectangular exr environment maps. Once loaded the data is converted as needed and passed to requesting objects. Environments are bound to jit.gl.node sub-contexts, and only a single environment can be active in the sub-context at a time. Cycling '74 glcore Jitter messages to this 3d object TEXT_HERE TEXT_HERE jit.gl.environment output TEXT_HERE dumpout TEXT_HERE Output the cubemap texture name TEXT_HERE Drag and drop image files for envirnoment map processing TEXT_HERE Make the active environment In contexts where multiple enironments are enabled, only a single environment can be active at a time. This message tells the context to make this environment the active one. The enable attribute must be on to make active. Upload the named texture data to the cubemap for envirnoment map processing TEXT_HERE Read in an image file for envirnoment map processing TEXT_HERE Adapt internal cubemap to input file dimensions Adapt the internal cubemap to input file dimensions on load (default = 1). Only effective when the internal cubemap is in use. When enabled edge_length has no effect. The named context or sub-context drawing destination The named context or sub-context drawing destination. When set, any supporting objects in the same (sub)context will have access to this envirnoment. Set length of the cubemap edge Set length of the cubemap edge (default = 64). Only effective when adapt is disabled and the internal cubemap is in use. Enable the environment map Enable the environment map for access by supporting objects in the same (sub)context (default = 1). Only a single envirnoment map can be active at a time, see the activate message for a convenient way to switch between enabled envirnoment maps. Set an image file to read with the internal cubemap Set an image file to read with the internal cubemap for envirnoment map processing. Enable gamma correction Enable gamma correction on the input (default = 1). Only effective when the internal cubemap is in use. Changing this value requires a re-load of the input file to have an effect. Environment map name TEXT_HERE Reflection Map Edge Length Set the length of the generated reflection map edge (default = 128). Higher values improve the resolution and perceived quality of PBR reflections (most notably on flat surfaces), at the expense of longer loading time and greater GPU memory usage. Changing this value causes the reflection map to regenerate, which will stall the renderer. Supporting objects include:
jit.gl.pbr
jit.gl.material
jit.gl.skybox

When used with PBR, irradiance and reflection maps are generated for IBL effects.

The object will process cubemaps based on requests from the supporting objects. The cubemap will either be stored internally, if loaded via read or jit_matrix messages, or external as the result of a jit_gl_texture message.
