multiview projection

Original address: http://android.xsoftlab.net/training/graphics/opengl/projection.html# #transformIn the OpenGL ES environment, the projected camera view simulates the drawing as a physical trait seen in reality. This physical simulation is achieved by changing the numerical coordinates of the object: Projection-This is achieved based on the Glsurfaceview's high-width coordinate transformation. If this calculation is not used, the objects dra

Objective Three.js is a 3Djs library, the WebGL Open source framework of the more excellent one. In addition to WebGL, Three.js also provides renderer based on canvas, SVG tags, and debugging suggests using Chrome or Firefox. 1. Camera The camera in graphics defines the projection mode of three-dimensional space to a two-dimensional screen. The camera is divided into orthographic projection camera and p

Of course it's just a solution.Next we wait for 5 seconds to make the bullet invisible and move it out of the basket, which will not affect the other shot, and can be reused.Final scoring, and update the score la

Settings of light, shadow, and camera in ogre1. To enable shadow, first call scenemanager: setshadowtechnique () and then call entity: setcastshadows () for the entity to be enabled ().2. The lights and cameras must be created by scenemanager, which are scenemanager: createlight () and scenemanager: createcamera ().3. you can create multiple cameras to manage ogre: viewport * Vp = mwindow-> addviewport (mcamera) with the view, and set the background color of the view using setbackgroundcolour ()
