camera drawing

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

. Here, we use some cloud brushes, which you can download to their photo-shop-brush.com at the address below. OK, after loading the brush, choose some clouds brush gently on the layer, I use the color is #2a6c9c. You should get the following results: OK, now add some flowers next to the camera: If you look closely, we simply cite 3-4 different flowers, download some of the flowers, and change their size and transparency. Make them look more laye

The camera lens is not ordinary glass, the surface will have some special material, the front looks will be colored. The overall method of production is similar to that of glass, except that it needs to be rendered in a variety of colors. The final effect of the Photoshop tutorial 1, first draw the approximate shape of the lens, with the Oval tool hold down the SHIFT key to draw a positive circle, plus the gradient and stroke, the following f

First, the camera working principleIn the previous article we talked about the composition of the camera module, working principle, as a kind of understanding. Let's analyze how the camera works from the register angle. How to read the camera spec (use key parameters for driver tuning, take GT2005 as an example).The sp

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

GLSurfaceView is a class in OpenGL and can also be used to preview Camera. It is unique in previewing Camera. Where is the uniqueness? When Surfaceview is powerless and hard to solve, GLSurfaceView can only be used. It can truly separate the data and display of Camera, for example, Camera only enables preview and does

Google has output TextureView from Android4.0. Why? This is to make up for Surfaceview's shortcomings. On the other hand, it is also to balance GlSurfaceView. Of course, this is my speculation. The relationships between TextureView, Surfaceview, SurfaceTexture, and GLSurfaceView will be analyzed after the artist launches GLSurfaceview preview Camera. This article describes how to preview Camera with Texture

The simple project we implemented in the previous article, and now we continue to add features for this camera. First, in Camera, we can perform simple control over the Camera.
