Android uses ndk instead of yuv420 overlay to ensure smooth video display. Instead, it uses a platform to port a safer rgb565 display. Tested on Android 2.3. However, the MTK andriod platform (a301) encountered a glteximage2d gl_error 0x501 error (the source image is 176*144 ). After repeated tests, this MTK andriod version supports OpenGL ES, but it has a strange limit on the resolution of the source image. When the source dimension width and height

Recently, due to interest, I began to learn OpenGL plotting. This article uses "Draw sphere" as a point to summarize what we have learned recently. > OpenGL ES started with OpenGL from Android. As we all know, Android View is thread unsafe, so it is only allowed to operate on the View in the main thread. However, if we need to implement a complex interface, especially for game development, and draw a large number of images in the main thread, it will

Introduction to OpenGL es:OpenGL ES (OpenGL for Embedded Systems) is a subset of OpenGL's three-dimensional graphics APIs designed for embedded devices such as mobile phones, PDAs, and game consoles . The API is defined by Khronos Group, Khronos is a graphic hardware and software industry Association, which focuses on the open standards of graphics and multimedia. The main new features of OpenGL ES 3.0 are:

The cube project has been around for nearly a month. The last important function module is gesture recognition, this will add a winning weight for the "2010 Google Android app development China College Student Challenge. Gesture Recognition is simple, just reload the method. The trouble is that glrotatef (float angle, float X, float y, float Z) in OpenGL ES ). This function is different from the glrotatef (float angle, float X, float y, float Z) funct

operand of OpenGL es Shader language (Official document, chapter fifth)5.1 OperandsThe OpenGL ES shader language contains the following operators.5.2 Array SubscriptThe array element is accessed through the array subscript operator ([]). This is the only operator that operates an array, and for example, an array element is accessed:Diffusecolor + = lightintensity[3] * NDOTL;5.3 Function callsIf a function h

OpenGL ES provides two methods to draw a space ry:Public abstract void gldrawarrays (INT mode, int first, int count) is drawn using vetexbuffer. The order of vertices is specified by the order in vertexbuffer.Public abstract void gldrawelements (INT mode, int count, int type, buffer indices), you can redefine the vertex sequence, which is specified by indices buffer.Mode indicates the vertices mode described above.As mentioned above, vertices are gene

The previous modelview transformation is equivalent to placing the camera and adjusting the position and angle of the object to be photographed. The projection transformation corresponds to adjusting the camera lens distance to obtain the scene.

The purpose of projection transformation is to define the Viewing Volume. On the o

Many tutorials say that the cocos2d-x OpenGL ES World coordinate system origin is in the lower left corner, but as to why in the lower left corner no one has ever mentioned it, which leads most people to think that this is OpenGL ES's rule, in fact it is wrong, OpenGL The coordinate origin of ES in the lower left or center of the screen is related to the projection matrix, if we set the Cocos2d-x projectio

Defining shapes is often the first step to develop high-end graphics. You do not need to know how OpenGL ES wants you to define image objects when Drawing Images Using OpenGL ES. The following describes the coordination system related and screens, and defines shapes, such as triangles and circles. Define a triangle: OpenGL ES allows you to define objects in a 3D
