问题 I am using this code from NEHE tutorial in my MFC based application on mouseclick void CRightOGL::OnLButtonDown(UINT nFlags, CPoint point) { // TODO: Add your message handler code here and/or call default GLint viewport[4]; GLdouble modelview[16]={0}; GLdouble projection[16]; GLfloat winX, winY, winZ; GLdouble posX, posY, posZ; GLfloat mv[16]; glGetFloatv( GL_MODELVIEW_MATRIX, mv ); glGetDoublev( GL_MODELVIEW_MATRIX, modelview ); glGetDoublev( GL_PROJECTION_MATRIX, projection ); glGetIntegerv

2D to 3D conversion using Dubois Anaglyph algorithm

由 Deadly 提交于 2019-12-05 05:17:14
问题 Hi I am attempting to convert a picture into a 3D equivilant, The method I am using is Dubois anaglyph Algorithm. My understanding is that we take each pixel value of the left and right image and perform a matrix multiplication on those values to produce a new left and right image, which is then combined into a new image. Is there something I am missing? Or is my understanding totally incorrect?. Here are some outputs from the code I have currently done: Image Here is some of the code I have

Convert 2d images to 3d model [closed]

I need to display 3d sculptures in my application, but all I will have initially is 2d images of sculpture from different angles( angle and count of images is under our control) 1. Is there any library which can do that, e.g. take 8 images from all side and stitch it into a 3D model? Any opensource/commercial library/product is ok. 2. Alternatively how difficult it would be to do if I start from scratch? what direction you would take e.g. Simple solution one 3D model is not a strict requirement, but the end result should be that user can rotate the object and see it from different angles so a

Ray Casting with different height size

由 北慕城南 提交于 2019-11-26 04:52:32
问题 I have a java project who makes the \"windows\' maze\" and use the ray casting algorithm. Here\'s a screenshot : Like you can see all the walls have the same height size. I would like to do the same but with different height size private void castRay(int xOnScreen,double angle,double direction) { R rx = castRayInX(angle,direction); R ry = castRayInY(angle,direction); // In case of out-of-space rays if (rx.getDistance()==Double.MAX_VALUE && ry.getDistance()==Double.MAX_VALUE) { graphics
