This document provides guidelines for 3D character, weapon, and environment modeling for a first-person shooter game. It recommends modeling body parts separately, using photo references, and spline-based facial modeling with wrinkle details added in Mudbox. Weapon models should use more polygons near the player's viewpoint. Level creation involves procedural tree modeling with Onyx Tree and exporting branches to 3dsmax to add texture details to lo-poly models.

The document provides instructions for 3D modeling assets for a first person shooter game, including character, weapon, and level modeling. It discusses using photo references and splines for facial modeling. Techniques covered include creating low-poly meshes from high-poly models, fixing mesh edges, UV mapping, normal mapping, and combining texture maps. Level creation involves using a procedural tree modeler and exporting branches to be broken down and rendered as textures to add detail to low-poly tree models.
TASK 2
This document discusses the process of 3D rendering and animation. It begins by explaining the initial modeling stage where objects are created using vertices, edges, and faces. It then discusses lighting models and how lights create shadows. Next it covers viewing through placement of the virtual camera, projection to create 3D illusion on 2D screens, clipping extra material, and viewport transformation of coordinates. It also discusses scan conversion to pixels, texturing, and final image display. The document concludes by defining rendering as converting geometry to 2D images and explaining common rendering techniques of rasterization, ray tracing, and radiosity.
Texturemapping
Texture mapping is a graphic design process that involves wrapping a 2D texture map around a 3D object to give it a surface texture. This technique is commonly used in 3D graphics and film visual effects. It involves correctly positioning the texture to account for the object's 3D geometry. Avatar extensively used texture mapping to create its virtual worlds and characters. Photographers can also use texture mapping by layering texture images over photos and adjusting settings like blending modes, hue, warp tools to enhance images. Students are assigned to find textures and photos to practice applying different textures as overlays and manipulating layers.
Rendering
Rendering is the process of converting 3D graphics into 2D images. There are several common rendering methods. Rasterization is commonly used in games and works by determining which triangles in a 3D scene will be visible from a given perspective. Ray tracing creates photorealistic images by simulating the paths of light in a scene, allowing for accurate reflections and refractions, but is difficult to implement in real-time games. Radiosity focuses on global lighting and shadows by tracking how light spreads throughout an environment.
Final Presentation
Deferred rendering is a rendering technique that allows for flexible lighting and effects by rendering the scene to textures first before applying lighting and shading. It works by rendering the scene to color and depth buffers, then applying textures, lighting, and effects in a pixel shader. While it has issues like memory usage, it enables many lights and complex effects. Atmospheric scattering simulates how light interacts with particles in the air to produce realistic skies and aerial perspective. It is complex to implement as it involves integrating scattering equations along light rays. While attempts to include it have been partially successful, it remains challenging to code and debug.

Hands-on with Umbra in Unity - Past, Present and the Future
Umbra is a company that develops 3D rendering optimization technology to improve performance for games and other industries. Their current product, Umbra 3, uses occlusion culling techniques to reduce rendering costs by culling objects that are not visible. Umbra is working on their next product, Umbra 4, which will allow unlimited 3D content to be streamed and rendered on any device by automatically restructuring and optimizing large datasets in the cloud. Umbra's roadmap includes integrating their technology into more tools and platforms to enable collaborative viewing of large 3D models across different applications and devices.
Task 6
Polygon count and vertex count are common measurements used to determine the file size and performance cost of 3D models. A high-end game character may use tens of thousands of polygons while a simpler mobile game may use only a few per character. While polygons are used to model 3D objects, games typically use triangles rather than polygons since graphics hardware is optimized for triangle rendering. Vertex count is more important than triangle count for performance, though artists typically refer to triangle count. Rendering is the process of generating images or animations from 3D scenes. Real-time rendering in games must be fast enough for interactive frame rates while non-real time rendering for movies can take seconds or days per frame for high image quality.

Datt 2500 week 10
Textures allow for adding detail to 3D models without increasing polycount. UV mapping involves projecting a 2D texture onto a 3D mesh using UV coordinates. Common texture types include diffuse maps for color and bump/normal maps for simulated surface detail without changing geometry. Displacement maps can actually modify the mesh geometry.
Gpu presentation
Graphics programming with Unity3D utilizes the GPU for highly parallelized operations like matrix and texture lookups. There are two main access points: shading which converts 3D to 2D, and post-processing which performs shader operations on the rendered image. The graphics pipeline involves vertex and pixel shaders transforming and coloring 3D models with effects like lighting, bump mapping, and textures. Multi-pass rendering and image effects allow combining results through scripts and shaders. Future improvements include deferred rendering, tessellation, and an expanded shader pipeline.

Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
