The values between the buffer’s current position and its limit are copied to the beginning of the buffer. The buffer’s position is then set to n+1 and its limit is set to its capacity. The buffer’s position is set to the number of floats copied.

WebCopies the remaining elements (as defined by limit() - position()) in the passed FloatBuffer into a newly-allocated direct FloatBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged. WebMar 21, 2013 · If you will be using them as offsets vertices [ (i+1)*3] = (float) (xOffset + Math.cos (2*Math.PI*i/lines)); (note '+' instead of '*') then 1st vertex should be at offset instead of (0,0) while texture coordinates remain the same.
