3D Arm Model

Prior to this degree, I had never made 3D models. One of my first deadlines was to create a model of an arm based off one image we were given, retopologize one vertebra by hand and one by automatic modifiers, create a 30 second animation, and one high quality still image. I took all the skills I learned over the first several weeks of this course to create my first ever complete anatomical model.

To begin, I gathered a variety of images to give different perspectives for each muscle in the arm. This allowed me to more accurately model the shape and size of the muscles relative to the rest. I then utilized some texture maps given to me by my lecturer as well as creating my own textures to apply to each muscle and tendon. Retopology on the vertebrae was the next challenge. One vertebra was retopolgized using a modifier in 3ds Max and the other was manually retopologized by created a new low poly model. Once everything was textured I created a background scene in a museum style layout with lighting and cameras which were used to create and render a 30 second animation.

Looking back at this project in the final month of this degree, having improved my skills, I can see many modifications that I would now make to create a much more realistic and organic model. However, for being my first ever organic, anatomical, 3d model this was quite an accomplishment and deserved to be shown in my showcase.

Final Image of 3d Models

This is the final image of my arm model (in the center) with the manual retopolized vertebra on the right side and the modifier produced vertebra on the left.

Initial Stages of Modelling

Using different images as a reference I began to create the 3d models of muscles, such as the biceps, and bones, such as the humerus, as seen in this image.

Whole Arm Without Texture

After creating a higher polygon model (20,000+ polygons), I then reduced it to around 6000 polygons for efficiency in the animation and to meet the brief requirements.

This was my final textured arm model which aligned with the original image I was given for recreation.

Final Scene Setup

This is the final scene setup for creating my final image and animation. Top Left Scene: Shows the right hand side of the setup with camera and lighting angles. Bottom Left Scene: Shows the top down view of the scene with camera and lighting angles in respect to the objects. Top Right Scene: Shows the front view of the scene setup in an orthographic view. Bottom Right Scene: Shows the view from the physical camera which was set up in the scene.
