3D Modelling
This subtopic covers the theoretical foundations of 3D modelling, including coordinate systems, geometry, and rendering, alongside practical skills in creating 3D models using industry-standard software. Learners will apply design principles and production workflows to produce models that meet a given brief, reflecting real-world media production practices.
Assessment criteria
Learning Objectives
What you need to know and understand
- Explain the principles of 3D space, including axes, vertices, edges, and polygons.
- Compare different 3D modelling techniques such as box modelling, edge extrusion, and NURBS.
- Devise a 3D model concept that meets a specified brief, including sketches and technical specifications.
- Create a 3D model using industry-standard software, applying appropriate geometry and topology.
- Apply textures, materials, and lighting to enhance the visual quality of a 3D model.
- Evaluate the final model against the original brief and industry standards.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating understanding of 3D coordinate systems and geometry.
- Award credit for producing a clear concept design with annotated sketches and rationale.
- Award credit for using efficient modelling techniques that result in clean topology.
- Award credit for applying textures and materials that align with the intended style.
- Award credit for reflecting on the modelling process and identifying areas for improvement.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always start with a clear brief and concept sketches to guide your modelling.
- 💡Use reference images to maintain accurate proportions and details.
- 💡Regularly save versions of your work and use non-destructive techniques where possible.
- 💡Check your model in different views and lighting conditions to spot errors.
Common Mistakes
Common errors to avoid in your coursework
- Using excessive polygons without considering performance or purpose.
- Neglecting to plan the model, leading to inefficient workflow and poor topology.
- Overlooking scale and proportion, resulting in unrealistic models.
- Failing to name and organise assets properly, causing confusion in production.
