So for example I havesuch lines with coordinates. how (using what algorithm) is it p开发者_如何转开发ossible to generate some kind of simple 3d scene meaning get relative distance from camera to the w
This is a basic question about the need for world and camera space matrices when each are identity matrices. Can they be omitted when calculating a 2D projection? I\'m pretty sure that they can, altho
Can anybody provide me with a quick code to implement depth 开发者_高级运维of field effect in OGRE?This thread post contains several links to DOF source + demo
I know you can do texture tiling/repeating in OpenGL by setting the texture coordinates to values greater than 1.0 (eg 2.0) but is there开发者_如何学C a way I can do texture tiling with the OpenGL tex
I\'m currently developing my own 3d engine, which has a ve开发者_Python百科ry limited abilities in terms of geometry rendering and I want to expand it. What I\'m interested in is how-it-should be done
FIXED by setting near clipping plane to 1, rather than 0 (not sure why it was like that to start with). See the question for skeleton code, and Adrian\'s answer for how and why this works.
I\'m looking for a way to automatically map a 3D mesh\'s polygons onto UV space such that texel density is maximized and k开发者_开发问答ept as consistent as possible between polygons. Does an algorit
Im attempting to convert a simple 3D room explorer/configurator app that is a hacky mess into something a little better.
I dumped some frames of a video and would like to generate a cuboid out of them, like in the following sample image:
in my previous code,I changed the coordinate system in my view\'s drawRect,so that the rectangle had 0,0in the centre, 0,1at the top centre and 1,0in the centre of the right edge. I.e. a normalised Ca
