GLU.gluCylinder(QUADRIC, RADIUS, RADIUS, height, slices, stacks);

GLU.gluDisk(QUADRIC, Inner RADIUS, Outer RADIUS, slices,

stacks);

GLU.gluSphere(QUADRIC,RADIUS, slices, stacks);

#DISPLAY LIST With GL_COMPILE

GL.glNewList(this.getListIndex(), GL.GL_COMPILE);

…

GL.glEndList();

GL.glBegin(TYPE);

GL.glVertex3f(AxisX,AxisY,AxisZ);

GL.glEnd();

#TYPES

GL.GL_POINTS

GL.GL_LINE_LOOP

GL.GL_LINES

GL.GL_QUADS

GL.GL_LINE_STRIP (CURVE -> Multi Line)

———-

translate

———-

GL.glLoadIdentity();

GL.glPushMatrix();

GL.glPopMatrix();

GL.glTranslatef(AxisX,AxisY,AxisZ);

GL.glRotatef(Angle, AxisX,AxisY,AxisZ);

———-

size

———-

GL.glPointSize(float size);

GL.glLineWidth(float width);

———-

colors

———-

GL.glColor3f(float red,float green,float blue);

GL.glColor4f(float red,float green,float blue,float alpha);

GL.glColor4fv(float args[]);

Effects

———-

GL.glBlendFunc() :

blend function’s source and destination rate setting.

EX)

GL.glBlendFunc(GL.GL_SRC_ALPHA, GL.GL_ONE_MINUS_SRC_ALPHA);

GL.glLightfv() : light setting.

EX)

GL.glLightfv(GL.GL_LIGHT1,

GL.GL_DIFFUSE,

new float[] {1.0f, 1.0f, 1.0f, 1.0f});

GL.glLightfv(GL.GL_LIGHT1,

GL.GL_AMBIENT,

new float[] {0.5f, 0.5f, 0.5f, 1.0f});

GL.glLightfv(GL.GL_LIGHT1,

GL.GL_POSITION,

new float[] {-50.f, 50.0f, 100.0f, 1.0f});

GL.glEnable() : enable effects.

EX)

GL.glEnable(GL.GL_BLEND);

GL.glEnable(GL.GL_LIGHTING);

GL.glEnable(GL.GL_COLOR_MATERIAL);
