ComfyUI Node: vec3

vec3:

The vec3 node is designed to create a three-dimensional vector, commonly used in graphics programming and shader development. This node allows you to define a vector with three components (x, y, and z), which can represent various attributes such as position, direction, or color in a 3D space. By providing a simple interface to input these values, the vec3 node helps streamline the process of working with 3D vectors, making it easier for you to manipulate and utilize these vectors in your projects. This node is particularly useful in GLSL (OpenGL Shading Language) contexts, where vectors are a fundamental part of shader programming.

vec3 Input Parameters:

x

The x parameter represents the first component of the 3D vector. It is a floating-point value that you can adjust to set the desired x-coordinate or attribute in the vector. The default value is 0.0, and you can increment it in steps of 0.01. This parameter is crucial for defining the horizontal component of the vector in a 3D space.

y

The y parameter represents the second component of the 3D vector. Similar to the x parameter, it is a floating-point value that you can adjust to set the desired y-coordinate or attribute in the vector. The default value is 0.0, and you can increment it in steps of 0.01. This parameter is essential for defining the vertical component of the vector in a 3D space.

z

The z parameter represents the third component of the 3D vector. It is a floating-point value that you can adjust to set the desired z-coordinate or attribute in the vector. The default value is 0.0, and you can increment it in steps of 0.01. This parameter is important for defining the depth component of the vector in a 3D space.

vec3 Output Parameters:

vec3

The vec3 output parameter is the resulting three-dimensional vector created from the input x, y, and z values. This output is a tuple containing the three components (x, y, z) and can be used in various GLSL contexts to represent positions, directions, colors, or other 3D attributes. The vec3 output is essential for any operation or function that requires a 3D vector input.

vec3 Usage Tips:

• Use the vec3 node to define positions or directions in 3D space for your shaders, ensuring that you have precise control over each component.
• Adjust the x, y, and z parameters incrementally to fine-tune the vector's attributes, which can help achieve the desired visual effects in your GLSL programs.
• Combine multiple vec3 nodes to create complex 3D transformations or animations by manipulating the individual components of each vector.

vec3 Common Errors and Solutions:

Invalid input type for x, y, or z

• Explanation: The x, y, or z parameter received a non-floating-point value.
• Solution: Ensure that all input values for x, y, and z are floating-point numbers. Use the default step of 0.01 to adjust the values accurately.

Missing input value for x, y, or z

• Explanation: One or more of the x, y, or z parameters were not provided.
• Solution: Make sure to provide values for all three parameters (x, y, and z) to create a valid vec3 output. If you want to use the default value, ensure it is explicitly set or left as 0.0.

Output not as expected

• Explanation: The resulting vec3 output does not match the intended vector.
• Solution: Double-check the input values for x, y, and z to ensure they are correctly set. Adjust the values incrementally and observe the changes to achieve the desired vector output.
