How can I transform them to make them line up? 回答1: The key to this is the call to 'Runtime.NuiCamera.GetColorPixelCoordinatesFromDepthPixel' Here is an extension method for the Runtime class. It returns a WriteableBitmap object. This WriteableBitmap is automatically updated as new frames come in. So the usage of it is really simple: kinect = new Runtime(); kinect.Initialize(RuntimeOptions.UseColor | RuntimeOptions.UseSkeletalTracking |

A teacher can teach many subjects and a subject can be taught by many teachers.my join table is subjects_teachers and have fields id,teacher_id and subject_id. Fetching Teacher data from its model, i expect all teachers and their respective subjects , Fetching Subject data from its model i expect to also see the teachers teaching that particular subject problem on both instances, the associated model returns the correct number of records but the data is absent. i see

When I display my color texture works fine, but my depthtexture is all white. Shouldn't it be like gray? my draw texture function: this.drawTexture = function() { //gl.viewport(0, 0, this.canvas.width, this.canvas.height); gl.clear(gl.COLOR_BUFFER_BIT | gl.DEPTH_BUFFER_BIT); gl.bindBuffer(gl.ARRAY_BUFFER, this.vertBuffer); gl.vertexAttribPointer(this.VertexPosition, 2, gl.FLOAT, false, 0, 0); gl.bindBuffer(gl.ARRAY_BUFFER, this

I've been working with the Kinect and attempting to capture data to MATLAB. Fortunately there's quite a few ways of doing so (I'm currently using http://www.mathworks.com/matlabcentral/fileexchange/30242-kinect-matlab ). When I attempted to project the captured data to 3D, my traditional methods gave poor reconstruction results. To cut a long story short, I ended up writing a

I realize this isn't quite the point of the algorithm, but I'm doing this as a test with breadth first and depth first searches to see what is fastest by timing them. The other two searches work as intended, but when I enter the same search information as my goal for the DFID search i get an empty list. So I know my data is right, just something in the algorithm is wrong and I can't figure out

It renders 2 trapezoids in same place, and one of them rotates. But the rotating one is always displayed on top, even though it should go behind the first trapezoid while rotating. I guess I messed up something with initializing OpenGL. Also while searching through stackoverflow i found a post where someone suggested to execute following code and see the output. int depth; glGetIntegerv(GL_DEPTH_BITS, &depth); printf("%i bits

I've constructed a sample here: http://jsfiddle.net/TheJim01/05up96m0/ The renderer on the left (the red knot) uses a standard linear depth buffer ( 1 to 1000 ). Selecting Perspective or Orthographic will re-render the scene with the selected camera type, and both appear to work as expected. The renderer on the right (the green knot) uses a logarithmic depth buffer ( 1e-6 to 1e27 ). As with the left sample, selecting a
