jit.gl.cubemap
Manage a cubemap texture target
Description
Maintains a cubemap texture target in an OpenGL context. It has 6 inputs -- one for each face of the cube. Cubemaps are typically used to map an environment for material effects such as reflection and refraction. When sent a texture to any inlet, jit.gl.cubemap adapts to the input type of the texture.
Discussion
This OB3D object optionally takes one argument: the name of a drawing context. This is a named instance of a jit.world, or jit.pworld object, or 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.
Arguments
None.
Attributes
adapt[int]
Enable adapt to input (default = 1). When enabled the texture output dimensions will match the input dimensions.
autotype[symbol]
read-only
Autotype
bordercolor[4 floats]
Sets the texture bordercolor
edge_length[int]
The length in pixels of a cube edge. Each face of the sube will be edge_length*edge_length in dimension.
file[symbol]
Sets an image file to read that is in panorama format
filter[symbol]
Filter applied to the texture.
gamma_correction[int]
Gamma Correction
level[int]
Specify mipmap level to write input data (default = 0). When level is non-zero inputs will overwrite the mipmap image at the specified mipmap level, where 1 is the largest resolution/nearest level. If necessary the data will be scaled for the appropriate level. The height and width of each level in the mipmap is a factor of two smaller than the previous level.
matrix_name[6 symbols]
read-only
The named matrix to access (default = none)
mipmap[symbol]
Texture mipmap interpolation style (default = none). A mipmap is a pre-calculated sequence of images, each of which is a progressively lower resolution. Mipmap interpolation is used for minification filtering, a technique for increasing efficiency by changing the amount of texture information displayed based on the position of the textured object in a 3D scene. When the area of the fragment in texture space is larger than a texel, a filtered (reduced size) copy of the texture is used instead. Thus objects that are close can use the highest resolution image, then swap for lower resolution copies as the object gets farther away. Setting mipmap to bilinear (better performance) or trilinear (better image quality) will enable automatic mipmap generation whenever the texture is updated.
Possible values:
'none'
'nearest'
'linear'
'bilinear'
'trilinear'
type[symbol]
Force incoming textures to a particular type. If set to auto, jit.gl.cubemap will adapt to the incoming type, otherwise they will be forced to the type specified.
Possible values:
'auto'
'char'
'float16'
'float32'
wrap[3 symbols]
Texture wrapping mode.
OB3D Attributes
automatic[int]
Automatic rendering flag (default = 1) When the flag is set, rendering occurs when the associated jit.gl.render object receives a bang message
drawto[symbol]
The named drawing context in which to draw (default = none) 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.
enable[int]
Enable flag (default = 1) When the flag is set, drawing is enabled.
layer[int]
Object layer number (default = 0) When in automatic mode, the layer number determines the rendering order (low to high). Objects in the same layer have no guarantee which will be rendered first.
name[symbol]
The instance name (default = UID)
Common Box Attributes
annotation[symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background[int]: 0
Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.
color[4 floats]
Sets the color for the object box outline.
fontface[int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname[symbol]
Sets the object's font.
fontsize[float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'
hint[symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.
patching_rect[4 floats]: 0. 0. 100. 0.
Aliases: patching_position, patching_size
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation[int]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 0. 0. 0. 0.
Aliases: presentation_position, presentation_size
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect[4 floats]
write-only
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size[2 floats]
write-only
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor[4 floats]
Sets the color for the object's text in RGBA format.
textjustification[int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
valuepopup[int]: 0
For objects with single values, enabling valuepopup will display the object's current value in a popup caption when the mouse is over the object or it is being changed with the mouse.
valuepopuplabel[int]: 0
Sets the source of a text label shown in a value popup caption.
Possible values:
0 = 'None'
1 = 'Hint'
2 = 'Scripting Name'
3 = 'Parameter Long Name'
4 = 'Parameter Short Name'
varname[symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.
Messages
(drag)
TEXT_HERE
bind
Sets binding of the cubemap to texture geometry.
equirect_matrix
TEXT_HERE
panorama_matrix
Load a matrix formatted in a cross shape containing every face of the cubemap. The panorama matrix layout is a cross shape holding the 6 faces of the cube. The faces are in a 4x3 grid where the rows are formatted as follows:

- nx pz px nz
- ** ny ** **
read
Read in a panorama formatted image file.
unbind
Unbinds the cubemap after a bind operation.
OB3D Messages
