Hey hey... Google has acquired Moto mobile... this doesn't mean that another apple has appeared... it's time to capture android... When I used to play Android, I transplanted several libraries. freeimage FreeType Tokamak to Android. Through ndk ..

1. Four pyramid: consisting of 4 triangles. Square Body: composed of 6 triangles. Difficulty: When building the vertex coordinates of a 3D space, you must always have the center coordinate of the object (0.0f,0.0f,0.0f) to rotate the object around

Elasticsearch-hadoop provides local integration of Elasticsearch with Apache Spark. The data read from Elasticsearch is operated in the form of Rdd in Spark, while the contents of spark Rdd can be converted into documents and stored in Elasticsearch

Due to my recent reading of h264 files, I encountered the problem of how to read the full frame data, through the use of Elecard Stream Analyzer tools, as well as the combination of "new generation of video compression coding standard--H264/AVC"

  The fog effect is actually very easy to implement. I will summarize it first: (1) first, we must set the background color to the fog color. (2) Enable the fog Effect (3) set the background color of fog (4) set the fog Equation The fog equation has

CodeNot very standard. Let's take a look. SDK version 15 can reduce the version compilation by itself. No new features are used. OpenGL currently has very few examples. If you are interested, you can download it and see it. It took me a day.All

If you reference an online record: For both, you pass OpenGL some buffers containing vertex data. GlDrawArrays is basically "draw this contiguous range of vertices, using the data I gave you earlier". Good: You don't need to build an index bufferBad:

you can define the shape you want to draw in OpenGL ES view, which is the first step in creating a masterpiece of high-end Graphics. It's a bit tricky to draw without knowing some basics, such as how OpenGL ES defines graphical objects.This tutorial
