Manage a GL shader Manages the process of compiling, binding and submitting a shader to OpenGL. A shader consists of both a vertex program and a fragment (aka pixel) program, which can be defined in a xml shader description file (JXS), or submitted individually. Currently the high level language GLSL, as well as ARB, and NV assembly programs are supported. Cycling '74 Jitter Jitter OpenGL messages to this 3d object TEXT_HERE TEXT_HERE matrix output if enabled TEXT_HERE dumpout TEXT_HERE Load a shader file Dragging a JXS file from the Max File Browser or desktop to a jit.gl.shader object, will load the file. Binds and compiles the shader object Manually binds and compiles the shader object. Compile the shader object Manually compiles the shader object. Double click to open the shader editor Double click to open the shader editor. If no file is loaded the editor will load a starter shader to use as the basis for a new shader. This file must be saved to disk for use after the editor is closed. Dispose and unload the current shader Dispose of and unload the current shader. Dumps shader data to the Max Console Dumps the indicated shader data to the max console window. Valid types are params, source, assembly. Clear the shader cache Clears the shader cache which stores loaded programs that have been compiled in order to minimize compile time for shaders that have already been compiled and have not been modified on disk. Report parameter defaults Sends the default data values for the indicated shader parameter out the right-most outlet. Get a parameter description TEXT_HERE Report shader parameters Sends the names of all the shader parameters out the right-most outlet. Report shader parameter data types Sends the name of the datatype for the indicated shader parameter out the right-most outlet. Report current shader parameter values Sends the data values for the indicated shader parameter out the right-most outlet. Load glsl vertex and fragment programs from disk Loads the given glsl vertex and fragment programs from disk. Load a glsl fragment program from disk Loads the given glsl fragment program from disk. Load a glsl vertex program from disk Loads the given glsl vertex program from disk. TEXT_HERE TEXT_HERE Opens the shader editor Opens the shader editor. If no file is loaded the editor will load a starter shader to use as the basis for a new shader. This file must be saved to disk for use after the editor is closed. Set a shader parameter value Sets the given shader parameter with the given atom values as defined in a JXS (Jitter shader) file. Set a geometry shader program parameter A geometry shader program parameter. Loads a JXS shader file from disk Loads the given JXS shader file from disk. Unbind the shader object Manually unbinds the shader object. Shader description file (JXS) The shader description file (JXS) to use (default = none) Enable Image Mipmaps TEXT_HERE Verbose output mode Enables or disables verbose output to the max console window (default = 0). Shaders can be attached to any OB3D thru the OB3D shader method. If the shader is attached to an OB3D, the OB3D will automatically manage the compiling and binding for the jit.gl.shader object. The jit.gl.shader object requires one argument: the name of a drawing context. A named drawing context is a named instance of a jit.window, jit.pwindow, or jit.matrix object that has an instance of the jit.gl.render object associated with it. Additionally it can reference the name of a jit.gl.node sub-context. This value may also be set via the OB3D drawto attribute. If no argument is present, the object is implicitly added to the first valid drawing context or sub-context found in the current patch or by searching up the patcher hierarchy.
