Some time ago, a film called dimensions: a walk through mathematics was published on the Internet. It is said that it details the four-dimensional space.

Code optimization Copy the Code code as follows: for ($i =0; $i Array_push ($week, $arr);} Copy the Code code as follows: for ($i =0; $i $week []= $arr [$i];}So there's no extra burden on the calling function. The advantages and disadvantages of building an index Benefit: The query will first go to the number of rows in the index list to target a specific value at a time, greatly reducing the number of rows to be traversed Cons: In any case to query this table, field a large number of du

2.1 create a camera: Position, target, and view frustum Before drawing the 3D world to the screen, you need the view and projection matrix of the camera. Solution You can save the camera position and direction in a matrix. This matrix is called a view matrix (view matrix, observation matrix ). To create a view matrix, xNa needs to know the position, target, and up vectors of the camera. You can also save the view frustum, which is actually visible

of the ball to 1 unit: Float minimumdistance = 1.0f; boundingsphere camerasstance = new boundingsphere (fpscam. Position, minimumdistance ); With the updated camera ball and model ball, you can detect the intersection between the two. If the intersection is detected, the camera is restored to the previous position: Boundingsphere origmodelsphere = (boundingsphere) mymodel. Tag; boundingsphere transmodelsphere = xnautils. transformboundingsphere (origmodelsphere, worldmatrix); If (camerasph
