Course content

11 sections • 39 lectures • 6h 59m total length

Introduction0:37
Project-Overview3:55
This is the real-world project you will be able to build after the completion of this course.
SETUP ENVIRONMENT0:06
RED TRIANGLE (Optional)45:11
In this lecture we are rendering simple red triangle, Please also download pdf with the code in the resources.
TRIANGLE WITH EXTERNAL COLORS10:20
Learn to render a triangle with external colors by supplying a color buffer and vertex attributes, then pass RGB data to the fragment shader.
MULTI-COLORED TRIANGLE9:01
Store vertex positions and rgb colors together in one array, then pass colors via a vec3 attribute to the fragment shader to render a red, green, blue multicolored triangle.
Translating Triangle5:01
Derivation of the trigonometric function rotations.0:15

Red Rectangle with two triangles9:36
Learn to draw a red rectangle in WebGL by composing two triangles from centered vertices on the canvas, using -0.5 to 0.5 coordinates, then experiment with colors.
Rectangle with triangle_FAN5:25
learn to render a rectangle in webgl by using a triangle fan with four centered vertices, assign per-vertex colors, and bind color buffers alongside position buffers.
Multi-colored rectangle5:45
Learn to create a multicolored rectangle in WebGL by assigning rgb colors to vertices, passing colors through a varying to the fragment shader, and adjusting attributes and strides.

gl-Matrix library file0:06
Proofs of matrics0:08
Transformation Matrices-code format0:06
Rotation with derived matrices28:11
This video will show you how we can apply matrices we derived from mathematics to actually rotate any object, I use triangle in this video but it can be applied to any object.
Translation with derived matrix21:07
Scale with Derived matrices19:12
Rotate Triangle with gl-matrix14:28
Rotate triangle with buttons21:39
Add rotation controls for a WebGL triangle by wiring HTML buttons to JavaScript rotation patterns that rotate the triangle along the x, y, or z axes via a matrix library.
Rotate and animate Triangle27:16

Create buttons to rotate in all directions(x,y,z)0:11
Code cube with buttons(x,y,z)14:16
Build an interactive code cube with x, y, and z rotation controls via buttons linked to IDs on a canvas. Use JavaScript event listeners and CSS to implement rotation patterns.
Use arrow keys to apply transformations0:11
Code cube controlling it with arrow keys17:35
Learn to translate a WebGL cube on a canvas with arrow keys, updating translation along the x and y axes for up, down, left, and right.

Requirements

Understanding of basic programming is required, but I will guide you through out the way.

Description

Welcome to "WebGL for Beginners: A Hands-On Guide." This course is perfect for students and professionals looking to dive into the world of WebGL and interactive 3D graphics.

As a student, I understand the challenges of learning new technologies and have made this course to be as accessible and engaging as possible. Your suggestions and encouragement are very important to us as we develop this course.

Technologies Used:

Visual Studio Code: For coding and development
JavaScript: Core programming language
HTML & CSS: For structuring and styling your projects.

Why this course?

Even though it was recorded using basic equipment, the content is highly useful and useful. Every topic will be covered practically so you can apply what you learn to real-world projects.

Your suggestions and encouragement are very important to us as we develop this course.

Join now to start your WebGL journey.

Course Focus:

Our approach in this course is hands-on from start to finish. While we won't be going through into the theoretical aspects of WebGL, I will provide supplementary materials for those who are interested in understanding the basic concepts.

I understand that as a student, you're looking to gain practical skills that you can apply directly. That's why this course is focused on giving you the hands-on experience you need to start building interactive 3D graphics for the web.
