I want to draw an Hexagon but i cant figure out how to set up the coordinates
right now i have something like.......
private short[] _indicesArray = {0, 1, 2, 6, 7, 8, 3, 4, 5, 2, 5, 7};
every three is a tr开发者_高级运维iangle... something like below /\ |/| /
Actually i found out how :)
indices_Array, is the order in which i want to draw my points
it is in the coordinates array where i specify my plotting points
float L = 0.15f; // this is length of each side//
float root;
//this will create a regular hexagon
private float[] initHexagon() {
root = (float) Math.sqrt(3)/2f;
float[] hexagon = new float[12];
hexagon[0]= L;
hexagon[1]= 0;
hexagon[2]= L/2f;
hexagon[3]= L*root;
hexagon[4]= -L/2f;
hexagon[5]= L * root;
hexagon[6]= -L;
hexagon[7]= 0;
hexagon[8]= -L/2f;
hexagon[9]= -L * root;
hexagon[10]= L/2f;
hexagon[11]= -L * root;
return hexagon;
}
glDrawArrays(GL_TRIANGLE_FAN, 0, 12); //use glDrawArrays to draw vertices
