Public Class methods |
objectType() |
Returns the FXDragType for FXGLObject
objectTypeName() |
Returns the drag type name
new(p, vis, tgt=nil, sel=0, opts=0, x=0, y=0, w=0, h=0) {|theGLViewer| ...} |
Construct GL viewer widget
new(p, vis, sharegroup, tgt=nil, sel=0, opts=0, x=0, y=0, w=0, h=0) {|theGLViewer| ...} |
Construct GL viewer widget sharing display list with another GL viewer
Public Instance methods |
lasso(x1, y1, x2, y2) |
Return an array of all objects in the given rectangle
setBounds(box) |
Change the model bounding box; this adjusts the viewer
fitToBounds(box) |
Fit viewer to the given bounding box
eyeToScreen(e) |
Translate eye-coordinate to screen coordinate. Returns a 2-element array [sx, sy] containing the screen coordinate.
screenToEye(sx, sy, eyez=0.0) |
Translate screen coordinate to eye coordinate at the given depth.
screenToTarget(sx, sy) |
Translate screen coordinate to eye coordinate at the target point depth
worldToEye(w) |
Translate world coordinate to eye coordinate
worldToEyeZ(w) |
Translate world coordinate to eye coordinate depth
eyeToWorld(e) |
Translate eye coordinate to eye coordinate
worldVector(fx, fy, tx, ty) |
Calculate world coordinate vector from screen movement
translate(vec) |
Translate object center
getBoreVector(sx, sy) |
Return boresight vector (an array of two arrays)
locked?() |
Returns true if the viewer is locked
readPixels(x, y, w, h) |
Read the pixels off the screen as R,G,B tuples.
readFeedback(x, y, w, h) |
Read the feedback buffer containing the current scene.
doesTurbo?() |
When drawing a GL object, if doesTurbo? returns true, the object may choose to perform a reduced complexity drawing as the user is interactively manipulating; another update will be done later when the full complexity drawing can be performed again.
turboMode?() |
Returns true if turbo mode is enabled
