Changeset 340 for experimental/distortionNG/distortionNG.cpp

Timestamp:

Message:

The intersection works and the selector highlighter is set and displayed correctly.
Next steps:

• use a variable to control whether distortion setup is active or not. temporarily track the Ctrl Key to enably(push or disable(release) the edit mode.
• Hide the highlighter and disable the intersection/drag tracking on diabled edit mode.
• catch up dragging values and translate them in the correct coordinate frame.
• apply dragging values:
• a) either on the texture coordinate while the grid is constant,
• b) or apply them on the grid node coordinates while the texture coordinates are constant (check/compare solutions!)
