Example 31 with FloatBuffer

use of java.nio.FloatBuffer in project jmonkeyengine by jMonkeyEngine.

the class MikkTSpaceImpl method getNormal.

@Override
public void getNormal(float[] normOut, int face, int vert) {
    int vertIndex = getIndex(face, vert);
    VertexBuffer normal = mesh.getBuffer(VertexBuffer.Type.Normal);
    FloatBuffer norm = (FloatBuffer) normal.getData();
    norm.position(vertIndex * 3);
    normOut[0] = norm.get();
    normOut[1] = norm.get();
    normOut[2] = norm.get();
}

Example 32 with FloatBuffer

use of java.nio.FloatBuffer in project jmonkeyengine by jMonkeyEngine.

the class MikkTSpaceImpl method setTSpaceBasic.

@Override
public void setTSpaceBasic(float[] tangent, float sign, int face, int vert) {
    int vertIndex = getIndex(face, vert);
    VertexBuffer tangentBuffer = mesh.getBuffer(VertexBuffer.Type.Tangent);
    FloatBuffer tan = (FloatBuffer) tangentBuffer.getData();
    tan.position(vertIndex * 4);
    tan.put(tangent);
    tan.put(sign);
    tan.rewind();
    tangentBuffer.setUpdateNeeded();
}

Example 33 with FloatBuffer

use of java.nio.FloatBuffer in project jmonkeyengine by jMonkeyEngine.

the class MikkTSpaceImpl method getPosition.

@Override
public void getPosition(float[] posOut, int face, int vert) {
    int vertIndex = getIndex(face, vert);
    VertexBuffer position = mesh.getBuffer(VertexBuffer.Type.Position);
    FloatBuffer pos = (FloatBuffer) position.getData();
    pos.position(vertIndex * 3);
    posOut[0] = pos.get();
    posOut[1] = pos.get();
    posOut[2] = pos.get();
}
