The semi-circle in front of the 16-meter area in field hockey is known as the "shooting circle" or "scoring circle." It marks the area from which a goal can be scored, and only goals scored from within this area are counted. Defenders are not allowed to enter this area unless the ball has left the circle. This rule is in place to ensure fair play and to prevent defenders from obstructing the attacking team's ability to score. **

To create a 3D glass bottle in semi-circle style with Blender, you can start by creating a cylinder shape and then scaling it down to the desired size for the bottle. Next, use the loop cut tool to create a semi-circle shape by selecting the top half of the cylinder and scaling it along the Z-axis to flatten it. Then, add a glass material to the bottle by adjusting the material properties such as transparency, roughness, and color. Finally, add details like a cap or label to complete the 3D glass bottle design. **
