3D Modeling: Assignment 1
In this assignment, we were required to create our own 3D model that includes various elements commonly found in a bathroom, such as a toilet, washbasin, mirror, window, floor, bathtub, and sink.
We were also asked to find reference images to guide our modeling process and ensure accuracy. In addition, we needed to pay close attention to the details of each object to make the overall scene look more realistic and well-designed.
For the sink, I started by creating a cube to serve as the main body. I then adjusted its position and scale, and removed the top face to create a box-like shape.
Next, I added a faucet on top of the sink, which was created using a torus to form the curved shape. I also modeled a drain at the center of the sink’s bottom using multiple cylinders to represent the drain structure.
Finally, I assigned materials and suitable colors to the sink to give it a more realistic appearance.
For the mirror, I used a cylinder as the base shape. I scaled it to a suitable size and applied a reflective material, using Blinn to simulate a mirror-like surface.
I then positioned the mirror above the sink, similar to how it would be placed in a real-world bathroom setting.
For the toilet bowl, I started by using a cylinder as the base shape. I then modified its proportions and adjusted the vertices to make it look more like an actual toilet bowl, with a smoother and more curved form.
To complete the model, I added a toilet seat and a toilet lid, carefully aligning them with the top of the bowl. I also created hinges to connect the lid and seat to the back of the toilet, just like in real life. These small details helped improve the realism of the model.
For the surface appearance, I assigned a green-colored material to the toilet bowl to give it a distinct look, making it stand out from other bathroom elements while still maintaining a ceramic-like texture.
For the bathtub, I started by modeling the main body using a scaled cube. I adjusted its shape to resemble a typical bathtub by rounding the edges and removing the top face to create the inner hollow area.
I added a drain at the bottom center of the bathtub, which was created using a small cylinder, placed and scaled appropriately to simulate a real drainage hole.
To enhance the realism, I also created a water pipe above the bathtub, which serves as the faucet. The pipe was modeled using a torus and cylinder combination, adjusted to look like it’s attached to the wall and positioned correctly above the tub.
Finally, I applied a smooth, glossy material to the bathtub to simulate a ceramic or acrylic surface, giving it a clean and polished look in the final render.
For the wall, I started with a large cube as the base. I then used the Extrude tool to hollow out the inside, effectively turning it into an enclosed room-like space. This approach allowed me to easily create the basic structure of the bathroom interior, with thickness and dimension for the walls.
By extruding from the cube instead of modeling separate planes, I was able to maintain a clean, continuous geometry, which made it easier to place other elements like the window, mirror, and sink accurately within the space.
For the window, I first selected a face on the wall where I wanted the window to be placed. I then used the Extrude tool to push the face inward, creating a window opening in the wall.
To make the window look more realistic, I added a frame around the opening using additional cubes, and inserted a thin transparent plane to represent the glass pane. I assigned a transparent material to the glass using a Blinn shader, allowing it to reflect light slightly while still being see-through.
The window helps bring light into the scene and adds a touch of realism to the overall bathroom environment.
