[ad_1] You can use OpenGL ES 2.0 on device that support it, older models of the iPhone (orginal and 3G) and iPod Touch ( 1g and 2g) do not support OpenGL ES 2.0. OpenGL ES 1.1 is available on all devices. [ad_2] solved Apple Inc. using OpenGL ES [closed]
[ad_1] When looking at the uv-coordinates and the vertex coordinates, one can see that they do not fit together: vertex ———————————————- 0.0f,0.0f,-1.0f, 0.0f, 0.0f, with,0.0f,-1.0f, 0.0f, 1.0f, <– vertex: change in x, uv: change in y with,heigh,-1.0f, 1.0f, 1.0f, 0.0f,heigh,-1.0f 1.0f, 0.0f In addition, you tell OpenGL in this line: GLES20.glVertexAttribPointer(mTextureCoordinateHandle, 3, GLES20.GL_FLOAT, false, 0, … Read more
[ad_1] I just looked at the source code, it would appear that Rokon just throws a random exception so it’s kinda tricky to trace where the issue is really coming from. I think your best bet would to be switching over to using the Java source code for the app and debugging it from there. … Read more
[ad_1] Sorry for my typo in the post… Here is how I managed to fix it: – (GLuint)make:(float[])meshVerts withSizeOfMeshVerts:(int)sizeMeshVerts { GLuint _vertexArray; GLuint _vertexBuffer; glEnable(GL_DEPTH_TEST); glGenVertexArraysOES(1, &_vertexArray); glBindVertexArrayOES(_vertexArray); glGenBuffers(1, &_vertexBuffer); glBindBuffer(GL_ARRAY_BUFFER, _vertexBuffer); glBufferData(GL_ARRAY_BUFFER, sizeMeshVerts, meshVerts, GL_STATIC_DRAW); } [ad_2] solved How to pass a vertex array as an argument in Objective-C?

[ad_1] I had a very positive experience in my experiments at writing a 2D “packman-style” game using Core Graphics: if you do it right, CALayer animation proves sufficiently reliable and simple to implement. Here is a link to a great article that explains how you can implement animated sprites in Cocoa. The trick is to … Read more
