Again, welcome to the second lecture of our course. In the previous lecture, we learned about three-point lighting. Today, we will focus on adding materials to our 3D models in Blender.
To add materials, we need to understand the concept of texture. For example, if we select an object and go to the material section, we can change the base color and see how it affects the object’s appearance.
To demonstrate this, let’s create a Python code in Blender that creates a UV sphere with 10 segments and 10 rings. Each face of the sphere should have a different material.
After running the code, we can see that each face of the UV sphere has a different material. However, there is an issue with the colors being the same for each face. We need to fix this by modifying the code.
To fix the code, we can use the loop attribute to assign a different color material to each face. After fixing the code, we can see that each face of the UV sphere now has a different color material.
Next, let’s see how the materials look in the rendering. We can switch the rendering engine to Cycles, which provides more realistic lighting and shadows. However, Cycles is slower compared to the real-time rendering engine EV.
We can also compare rasterization and ray tracing, which are two different techniques used in rendering. Rasterization is used in vector graphics and real-time rendering, while ray tracing is used in Cycles for more realistic lighting, shadows, and reflections.
In Blender, we can add a camera to our scene and render the image using Cycles or EV. Cycles provides a more realistic result, but it takes more time to render. On the other hand, EV provides real-time rendering but compromises on quality.
In conclusion, we have learned how to add materials to 3D models in Blender. We have also explored the differences between Cycles and EV rendering engines, as well as rasterization and ray tracing techniques. In the upcoming lectures, we will cover animation in Blender. Thank you for watching!
