Working to a Brief

Trash Box

Overview

For this assignment, we had to model a box of trash while following a fixed set of technical requirements.

Specification

Style – photo realistic and must be accurate to references

Reference – source other references

Scale: centimetres – one unit = one centimetre

Polygon count: 500 triangles

Texture space: 1 RGB texture @ 1024 x 1024 pixels square. Save as Targa (.tga)

Efficient use of polygon budget – distributed intelligently so areas with more details have more polygons

Orientation and position – centre point must be placed at World (0,0,0)

Gantt Chart

PlannedScene

I went into the green screen room to take images of my

chosen rubbish put together. I chose to take the

photos using the green screen in case I needed to

edit the photos in Photoshop. I took images from two different angles

but I decided to use the second image (see bottom)

as it showed more of the rubbish in the scene. I used this as my reference image.

Cereal BoxThe boxes in the scene were very easy to model. To create the cereal box, I drew a box and used the ‘Boolean’ tool to hollow it out. I then used the Unwrap UVW modifier to create an unwrap for the box which I saved as a .png. I then added the textures to the unwrap in Photoshop which were saved as a Targa file (.tga) and applied it to my box.

Ice Cream Box

The ice cream box had less sides so I used the ‘Boolean’ tool (see below) to cut out the sides. This resulted in a hollowed box with 4 sides (see bottom right). However, the shape didn’t represent the reference image very well so I converted it to an editable poly and pulled the top up to bring it out from the square shape (see right). I then used the same method to texture it.

Cardboard BoxThe cardboard box is the model I am happiest with. I think this is due to the detail and the accuracy I had with the textures. The renders below show an angled version of the box and a render from the bottom. The cardboard box is made out of 4 boxes for the flaps and a box that has been hollowed out using the ‘Boolean’ for the main section.

Wine Bottle

The image on the left shows my first attempt at modelling a wine bottle. However, because the number of triangles was nowhere near the 500 limit, I chose to redo it to make it appear smoother.

The render on the right shows the redone version with its textures. I found the wine bottle the hardest to texture simply because of the circular shape as I have always founds these harder.

First Scene Setup

This is my first setup of my scene following the reference image I had chosen. If you look at the polygon count below, this is why I chose to redo the wine bottle with a higher number of triangles. Looking at this scene, I decided that you would barely be able to see the bottle behind the cereal box. Because of this, I chose to change my scene.

Final Scene Setup

This is my redone scene and I set it up so all the rubbish would be easier to view by placing them at different angles. With the bottle added, the polygon count has gone up a lot but I was still able to remain under the 500 triangle limit.

Texture Map

To show my textures, I create a single texture

map that contains all the textures from my

scene.

I decided this was a better way to

demonstrate it rather than showing lots of

individual maps. I kept it on a black

background though I changed this later on

to match the colour of my portfolio board.

Final RendersThese are my final renders; on the right is my final scene and the one below demonstrates the wire frame of my models.

I chose to render it onto the blue background because I had chosen this colour for my portfolio board and I wanted the render to merge well into the background.

Revised Gantt Chart

After completing my project, I redid the Gantt chart to show how my time was actually split. Compared to my previous Gantt Chart, I found that I had to spend more time than expected on most of the sections. However, I believe that this is more due to poor time management on my part.

If I were to redo this assignment, I would definitely look at getting the basic modelling and texturing done a lot earlier. I also would have taken a better record of my measurements as a lack of recording them is what caused me to spend longer on it as I had to measure some of my objects again.
