I\'m trying to render some 3d graphics with a bunch of tetrahedra. I\'m 开发者_高级运维trying to figure out how to rotate one tetrahedron such that it will be perfectly face-to-face with another tetra
I have a table with the following schema in MySql 5.1: Venue (id, name, location) where location is of type Point.
I am trying to figure out how to clear circles off the map that allows users to draw a radius around a point. My clearMap function doesn\'t seem to work. See code below
I\'m trying to implement marching cube algorythm in my geometry shader. So i place my datagrid into a Texture3D. Now i want to look up the data in the geometry shader and this trows an error \"cannot
We can create a LineString using coordinates list like开发者_Go百科 this: Geometry g1 = new GeometryFactory().createLineString(coordinates);
I created a map which allows users to draw a circle around a point with a specified radius. For some reason the circle does not get completely filled in and this is especially noticeable when the map
How would I convert a \"normal\" rectangle into a set of OpenGL ES vertices. I\'m not good at geometry so I have no idea how vertices work, and I want to be able to manipulate rectangles without havin
Given an arbitrary 3D mesh, I\'m looking for an algorithm that would perform hidden-line removal in real-time. I\'m working in the context of OpenGL, which means that we can take advantage of the Z-Bu

I have 3d body (triangle mesh) and a surfuce normal to one of the faces. I want to rotate the body such that the Z axis would be parallel to the normal. How 开发者_开发问答to find the rotation matrix?
