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 languages GLSL and CG, 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 arb programs from disk Loads the given arb vertex and fragment programs from disk. Load an arb fragment program from disk Loads the given arb fragment program from disk. Load an arb vertex program from disk Loads the given arb vertex program from disk. Binds and compile the shader object Manually binds and compiles the shader object. Load a shader file When a shader file is dragged from the Max File Browser to a jit.gl.shader object, the file will be loaded. 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. Compile the shader object Manually compiles the shader object. TEXT_HERE TEXT_HERE 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. 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. 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. 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. TEXT_HERE TEXT_HERE 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 compiler The compiler to use for compiling shader programs. (default = native) Supported compilers are:
native (native compiler in graphics driver)
internal (internal jitter compiler) Shader description file (JXS) The shader description file (JXS) to use (default = none) Matrix Output TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Preferred language The language to prefer if multiple programs have been specified. (default = none) Supported options are:
none
glsl
cg
arb
nv 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.
