Spread the loveSOLVED! Android Studio AMD CPU ERROR: x86 emulation currently requires hardware acceleration This Android Studio Error can be quite confusing. Then, download Intel x86 Emulator Accelerator (HAXM, for Mac and Windows only). This will enable the virtual machine acceleration capabilities of the Intel CPU from Android SDK Manager –> Tools.
Create Primitive Object Using OpenGL ES on Android (Part 1): Computer graphics is the part of computer science that is relating to create, manage, processing and manipulation of images (visual) digitally. Or we call it that computer graphics, it’s the inverse of computer vision. If the computer vision is to change the image / graphic into a information, while computer graphics is to convert the information into a form of visualization images / graphics. Primitives objects is an important part in computer graphics, because by understanding it, meaning you will be able to have an overview of how when creating objects that are very complex.
In this tutorial using the concept of Primitive Objects on Computer Graphics is without any shader or OpenGL Shading Language (GLSL), it’s pure only using OpenGL ES elementary syntax. Here we give some examples of primitive objects that will be created using the OpenGL ES 10/20 OpenGL ES on Android devices: By Android Student Community. • What’s Primitives “ Primitives Objects” is a simple/basic geometry that consisting of: points, lines, rectangles (quads), and triangle. And it is actually, anything complex object is can be representing/ created by combining these primitive forms. • How to create Points To create/ make the dots/ points in the OpenGL ES 1.0 or OpenGL ES 2.0 on Android it’s very simple.
Y ou only need to specify the points in the array, either manually or using the iteration program (Looping for) to generate it. • How to create Lines with Points Here we use the equation of a straight line calculated from two points that are known to use “Digital Differential Analyzer (DDA) Algorithm“.
Example is the two points (x1, y1) and (x2, y2) which will be used to calculate the value of the gradient (m) or the slope of the line, with the following formula below: m = (y2 – y1)/(x2 – x1). (1) Then for generate all points that you will draw, will be quite simple if you use “Looping for” could be carried out based on the lower bound and upper bound for interval the value of x = [xminxmax], or that it run with it the value of interval y only. Here the equation of a straight lines: y = mx + c. Links golf video game for mac. (2) Details d escription: y-y1 = m(x – x1).
(3) So, y = mx – mx1 + y1. (4) y = mx + (y1 – mx1). (5) In the equation (5), c = (y1-mx1) Description for every varibles: y = is the dependent variable, which will be calculated by the value of the input value x. X = an independent variable that determines the value of y. C = a constant, intercept or shift or bias of the “equation” on the x-axis or the y-axis.
And the direction can be “top –down” or “right –left” or form a certain angle. Note: In addition to “DDA Algorithm”, you can also use the “Bresenham’s line algorithm,” or using other techniques to be implementation utilize OpenGL ES on Android.

Screenshoot create Points and Line with Points via Eclipse n Bluestacks The simple method to tracking variable via log.v On Android: Try type like this “tag:value.loop_” without quotes on search “verbose”. Tutorial Practice Prepare Coding OpenGL ES (Embedded System) to Configuration “Eclipse + Bluestacks” On Android: This following steps are used to overcome / re-solve / fix some of the problems / troubleshooting / error / failed are often encountered/ founded when you do any coding or debugging OpenGL ES android application via Eclipse, especially to connect Eclipse with alternative emulator, for example, how to connect Eclipse with Bluestack player application and Eclipse with Mobile Phone (In this tutorial, we are use Samsung gt-i9070 Galaxy S Advance Android smartphone). And after we tried a few alternatives other emulators, we conclude that the Bluestacks + Eclipse is very awesome.
