🌟 Course Overview 🌟

The course has received a global rating of 4.35 from recent reviews. It is aimed at beginners who are looking to learn shaders in OpenGL/WebGL from scratch. The content is generally well-explained, making it a highly recommended resource for those starting out with shaders and image processing in the context of WebGL.

Pros:

• Comprehensive Content: The course covers the basics very well, providing a solid foundation for beginners. It is praised for its good coverage and clear explanation of fundamental concepts.
• Real-World Application: Students who completed the course report feeling confident in their ability to work with shaders after applying what they learned.
• Pacing and Progression: The pace of the course is commended for being spot on, with a progression that feels exactly right for new learners.
• Educational Approach: The course's approach to demonstrating basic concepts has been effective, and there is an anticipation for more advanced content in future courses, particularly concerning GLSL.
• Engagement and Usefulness: The course engages students effectively, with some learners finding it a brilliant idea to create a utility library as part of the learning process.
• Supportive Learning Experience: The course provides helpful content and is appreciated for making fundamental knowledge of WebGL easily accessible.

Cons:

• Repetition: Some reviewers have pointed out that there is too much repetition in the course, with the same lines of code being repeated unnecessarily.
• Overlooked Fundamentals: A few reviews mention that fundamental concepts such as what a fragment shader or vertex shader is are not covered initially, which might leave some students confused.
• Prior Knowledge Required: It has been noted that students need to have prior knowledge of OpenGL to fully understand the course material, as some content jumps into assuming familiarity with certain concepts and terminology.
• Ineffective Teaching of Basic Terminology: Some learners found that basic terms were used without being properly defined at the beginning, which could lead to misunderstandings or the need for additional research outside the course.

In summary, while this WebGL course is highly recommended for beginners due to its well-explained content and effective teaching of fundamental concepts, it has some areas that could be improved by reducing repetition, defining basic terms from the outset, and ensuring a smoother transition into more advanced topics for those without prior OpenGL knowledge.
