In this lesson, we will focus on three fundamental modeling techniques: extrusion, scaling, and rotation. These techniques will allow you to create complex shapes from basic forms, essential for designing engaging 3D environments.

Extrusion is a powerful technique that allows you to extend a shape into 3D space. By selecting a face of a mesh and pulling it outward, you can create walls, floors, and other structural elements.

Tip: Always consider the flow of your geometry when extruding. This will help maintain clean topology, which is vital for texturing and animation later on.

Scaling allows you to adjust the size of your models. This is particularly useful when refining the proportions of your environment objects.

# Example of scaling an object in Blender
import bpy

# Select the object
obj = bpy.context.active_object

# Scale the object
obj.scale = (1.5, 1.5, 1.5)

In this example, we scale the selected object by 1.5 times its original size. This is useful for adjusting the height of buildings or the size of props to fit your environment.

Rotation is essential for positioning your models correctly in the 3D space. It allows you to orient objects in a way that enhances the overall composition of your scene.

Common Mistake: Forgetting to apply transformations can lead to unexpected results when exporting your models. Always apply your transformations before finalizing your model!

Foundations of 3D Modeling

UV mapping is the process of projecting a 2D image texture onto a 3D model's surface. This technique allows artists to wrap textures around their models, giving them depth and realism. The term 'UV' refers to the axes of the 2D texture space, as opposed to the XYZ axes of the 3D model.

Understanding UV mapping is essential for several reasons:
- **Texture Application**: Proper UV mapping ensures that textures are applied correctly, avoiding distortions and misalignments.
- **Visual Quality**: Well-mapped UVs enhance the overall visual appeal of a model, making it more engaging in a game environment.
- **Efficiency**: Efficient UV layouts can optimize texture usage and improve performance in game engines.

🔍 **Tip:** Always aim for a uniform distribution of UV islands to minimize texture stretching and maximize detail.

When a texture is applied to a model, the UV map dictates how the 2D image corresponds to the 3D surface. If the UVs are poorly laid out, the texture may appear stretched, compressed, or misaligned, which can detract from the model's realism.

There are several UV mapping techniques you can use, including:
- **Unwrapping**: This technique involves flattening a 3D model’s surface into a 2D representation, allowing for precise texture placement.
- **Box Mapping**: A quick method that projects textures from multiple sides of a model, useful for simple shapes.
- **Cylindrical and Spherical Mapping**: These methods are ideal for cylindrical or spherical objects, wrapping textures around them seamlessly.

Hands-On Exercise: Creating a UV Map in Blender
