3D Banner Text Generator

Rendering volumetric text in a 2D space requires simulating depth through programmatic layering. This generator utilizes a technique known as the Painter's Algorithm on an HTML5 Canvas to iteratively draw text from back to front, creating a convincing pseudo-3D extrusion. Because all rendering happens directly on the client's GPU via the browser's graphics pipeline, there is zero server latency, allowing for real-time visualization.

Users must carefully balance the d (depth) and θ (angle) parameters to prevent the extrusion from clipping outside the designated canvas boundaries. This tool accurately calculates text metrics to perfectly center multi-line typographical blocks, making it highly effective for generating precise, high-resolution graphic assets for social media headers, digital marketing campaigns, and video thumbnails without the overhead of heavy 3D modeling software.

The 3D extrusion effect is achieved by calculating Cartesian offsets for each incremental layer of depth. For a total depth of D and an angle of θ, the precise coordinates for layer i are determined using standard trigonometric projection.

Where:
x₀, y₀ = The center point coordinates of the text block.
i = The current depth iteration ranging from D (background) to 0 (foreground).
