Here's a summary of what people are saying about the course "WebGL Fundamentals - A Beginner's Guide to GLSL Shaders & WebGL with Three.js" taught by Nik Schutz:

Positive Feedback:

• The course provides a solid introduction to GLSL shaders and their application in Three.js.
• Nik's teaching style is clear, humorous, and accessible, accommodating learners of different skill levels.
• The course is well-structured, offering essential topics that are fundamental for understanding WebGL and shaders.
• It is praised for making intricate topics like shaders understandable.
• The course allows learners to revisit key concepts, which reinforces learning and enables practical application of knowledge.
• Many users appreciate the inclusion of real-world examples and the practical approach to learning.
• The course is considered a good starting point for those new to shaders, and it helps in building experience with GLSL.

Areas for Improvement:

• Some users note that the course occasionally contains outdated GLSL references or uses deprecated variables, which may need updating for current best practices.
• A few learners found the course to be a bit all over the place at times, with some content feeling rushed or less well-explained.
• There are mentions of the course being heavy on JavaScript setup before diving into GLSL, which could be perceived as a balance between too much JS and not enough focus on the shader logic itself.
• Some learners express a desire for more hands-on assignments to apply the concepts taught throughout the chapters.
• The inclusion of background music in later lessons is noted as being potentially distracting.
• There are suggestions that the course could benefit from more detailed explanations, particularly regarding the underlying math and the actual shader logic, rather than relying on "magic numbers" and unexplained functions.
• Learners find some of the code examples to be complex with long lines and would prefer more descriptive variable names for better readability and understanding.

General Observations:

• The course seems to be a mix between introductory material and deeper technical explanations, which can be valuable but also might require the learner to have some prior knowledge or a higher tolerance for abstraction.
• There's an expectation that learners might benefit from additional resources or supplementary material on the fundamentals of graphics programming and mathematics.
• The course is recommended as a starting point even for experienced CG programmers looking to understand WebGL and shaders within the Three.js framework.

Overall, the course appears to be a valuable resource for beginners and intermediate learners looking to understand and work with GLSL shaders in the context of WebGL using Three.js. It is commended for its structure and practical approach but also highlighted for areas that could be improved for clarity and relevance to current standards.
