jit.gl.skybox
Render a skybox in OpenGL
Description
The jit.gl.skybox object renders a skybox in a opengl world. A skybox is a cube that remains infinitely far away from the camera, and gives the illusion of distant 3D surroundings. The jit.gl.cubemap object is used to texture the skybox.
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.
Attributes
infinite[int]
When enabled the skybox is rendered at an infinite distance from the camera (default = 1).
OB3D Attributes
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.
name[symbol]
The instance name (default = UID)
quat[4 floats]
The current rotation as a quaternion(default = 0. 0. 0. 1.). A quaternion is a mathematical construct that is a four dimensional vector, and can be visualized as a rotation around an arbitrary axis. Quaternions are a useful representation of an orientation in 3D space.
rotate[4 floats]
The angle of rotation and the xyz vector about which the rotation is performed in the form rotation-angle x y z (default = 0. 0. 0. 1.)
rotatexyz[3 floats]
Sets the current rotation to the concatenation of rotations about the positive x, y, and z axes, also known as Euler angles (default = 0. 0. 0.). The default order is yzx and can be changed with the jit.gl.render rotate_order attribute. Angles are expressed in degrees.
scale[3 floats]
The 3D scaling factor in the form x y z (default = 1. 1. 1.)
texture[8 symbols]
The name of the texture to be applied (default = none). If multiple textures are specified, uses multi-texturing.
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
OB3D Messages
bang
Equivalent to the draw message.
draw
Draws the object in the named drawing destination. If the matrixoutput attribute is supported and set to 1, the geometry matrices are sent out the object's left outlet.
drawraw
Equivalent to draw with the inherit_all attribute set to 1.
drawimmediate
Equivalent to draw but ignoring any potential renderer setup
jit_gl_texture
Binds the texture specified by texture-name to this object. Equivalent to setting the texture attribute to texture-name .
- texture-name
