I have a triangle in (u,v) coordinates in an image. I would like to draw this triangle at 3D coordinates (X,Y,Z) texture-mapped with the triangle in the image.
I\'m开发者_StackOverflow learning metapost and i want to know how to generate a figure like a polygon number http://en.wikipedia.org/wiki/Polygonal_number , i got triangular numbers but not hexagonal.
I\'m trying to test whether a given point开发者_StackOverflow社区 (x, y) is located on or close to the outline of a QGraphicsPathItem.
technology: WPF, C# pretext: I am making a game with a custom gyroscope+accelerometer device. I have a sphere that has a labyrinth map on it. The texture is mapped by a set of positions and texture c
I\'ve got a right triangle and I want to check if a given point is on the Hypotenuse of that triangle. All points are plain integers, not floating-point variables.
The idea is to get rating control, that could have value like 0.3 and draw it as partly filled shape.
I have most of the code that works [self.开发者_如何学运维disclosureButton setBezelStyle:NSDisclosureBezelStyle];
Our VB.NET project is using a Java library from Vivid Solutoins (com.vividsolutions.jts.geom.Geometry) to do Geometry calculations.The help is here: http://tsusiatsoftware.net/jts/javadoc/com/vividsol
In 3D space, given P1 and P2, and two links attached end to end with lengths L1 and L2 respectively, link1 starts at P1. Write a function that finds the configurations of the links that put the开发
I have the start point (x1,y1) and the desired length and angle of the line. If the angles were directions, 0 degrees is W, 90 is N, 180 is E and 270 is S. I can modify this if needed.
