Unigine::Plugins::SpiderVision::WarpGridData Class
Header: | #include <plugins/Unigine/SpiderVision/UnigineSpiderVision.h> |
The object of this class stores the information on the warp grid — a set of points and their handles that create a mesh based on which the displayed image is reshaped.
Warping of the image is required to render the projected image on a distorted surface in such a way that it would look undistorted.
This object is accessible via the corresponding method of the ViewportData class.
The mask data are stored in the configuration file.

Members
void setGridSize ( int row, int column ) #
Sets the number of columns and rows on the warping grid.Arguments
- int row - Number of grid rows.
- int column - Number of grid columns.
void setPoint ( int x, int y, const Math::vec2 & point ) #
Sets the coordinates of the warping control point on the grid.Arguments
- int x - Position of the warping control point in the row, starting from 0 on the left.
- int y - Position of the warping control point in the column, starting from 0 at the bottom.
- const Math::vec2 & point - Screen-space coordinates of the point.
void setPoint ( int index, const Math::vec2 & point ) #
Sets the coordinates of the warping control point on the grid.Arguments
- int index - Warping control point index. The point with the 0 index is in the bottom left corner with the progression going upwards, and then to the next column bottom point.
- const Math::vec2 & point - Screen-space coordinates of the point.
Math::vec2 getPoint ( int x, int y ) const#
