Process texture data Generate, process and combine images efficiently using fragment shaders. Develop custom texture effects for processing on the graphics card. 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.slab object, will load the file. 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. Report slab shader parameter's default value TEXT_HERE Get a parameter description TEXT_HERE Report slab shader parameter names TEXT_HERE Report slab shader parameter's type TEXT_HERE Report slab shader parameter's value 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 slab shader parameter value TEXT_HERE Loads a JXS shader file from disk Loads the given JXS shader file from disk. Sends an input texture a message Sends a message to an input texture. If the first arg is an int, it specifies the texture index to send the message, otherwise all input textures receive the message. Sends the output textures a message Sends the output jit.gl.texture objects a message. Sends the internal shader a message Sends the internal jit.gl.shader object a message Current input number The current input used for texture and matrix messages (default = 0). Useful when calling input messages from Java or JavaScript. Enable adapt to input Enable adapt to input (default = 1). When enabled the texture output dimensions will match the input dimensions. Texture color mode Texture color mode (default = argb) TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Depth TEXT_HERE Texture output dimensions The texture output dimensions when adapt is disabled (default = 256 256) Output dimension scaling factor The output dimension scaling factor of the output (default = 1 1). Useful for upsampling or downsampling texture output.
output.dim = input.dim*dimscale Displaylist TEXT_HERE Edges TEXT_HERE Shader description file (JXS) The shader description file (JXS) to use (default = none) Slab input count Slab input count (default = 2) Output texture name TEXT_HERE Number of texture outputs Number of texture outputs (default = 1). Texture outputs correspond to shader render targets. For an example of multiple render targets see mrt.slab.unpack Slab geometry rectangle Slab geometry rectangle (default = 0 0 1 1). The four values represent normalized coordinates for the left, bottom, right and top sides of the geometry rectangle. To flip the image horizontally use rect 1 0 0 1 or to flip vertically use rect 0 1 1 0. Enable texture rectangle mode (default = 1) Enable texture rectangle mode on internal texture objects(default = 1). When enabled the internal GL texture is treated as a rectangular texture, and must be referenced using sampler2DRect and sampled using texture2DRect when sampled from a GLSL shader. When disabled the texture dimensions are upsampled to the nearest power of two value, and must be referenced and sampled using sampler2D and texture2D. Certain texture attributes and GLSL effects require rectangle mode disabled. Enable thru mode Enable thru mode (default = 1). When the flag is set, texture output is sent whenever input is received. Slab geometry shape TEXT_HERE Slab geometry subdivisions The number of subdivisions to use for generating grid based geometry (only valid when shape == grid) Texture rectangle Texture rectangle mapping values (default = 0 0 1 1...). The four values represent texture mapping coordinates for the left, bottom, right and top sides of the geometry rectangle, and can be used to easily crop the input image. There are four values for each texture input. Output texture data type The output texture data type (default = auto). When type is auto the type is set by the input texture or matrix type. Adapt to input data type TEXT_HERE 8bit unsigned byte TEXT_HERE 32bit integer TEXT_HERE 16bit float TEXT_HERE 32bit float TEXT_HERE 16bit float TEXT_HERE 32bit float TEXT_HERE Wrap TEXT_HERE This 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.
