Abstract
Locations in a pattern of a part are evaluated to determine if the locations are interior or exterior to a feature of the pattern. The pattern is used to cut the feature from a material by a laser cutting machine. A location in the feature is rendered into an array stored in a memory so that a value stored at an address in the array corresponding to coordinates of the location is either odd or even as determined by a counting process of the rendering. Then, the location is identified as being interior if the value is odd, and as being exterior if the value is even. The rendering can use modified forms of either rasterization or ray casting.
Claims25
A method for evaluating whether a location in a pattern of a part is interior or exterior to a feature of the pattern, wherein the pattern is used to cut the feature from a material by a laser cutting machine, comprising the steps of:
- rendering, at the location, the feature into an array stored in a memory so that a value stored at an address in the array corresponding to coordinates of the location is either odd or even as determined by a counting process of the rendering;
- and
- identifying the location as being interior if the value is odd, and as being exterior if the value is even, wherein the steps are performed in a processor.
A laser cutting machine, comprising:
- a cutter head;
- a memory configured to store an array, wherein addresses of the array correspond to coordinates of locations in a pattern of a part to be cut by the laser head from a material;
- a processor configured to render a feature in the pattern into the array so that each value stored at one of the addresses is either odd or even as determined by a counting process of the rendering, and identifying each location as being interior if the value is odd, and as being exterior if the value is even.
