Vector Graphics

Vector graphics methods provide additional drawing features such as Bézier curves, rounded rectangles, SVG paths, and stars.

Methods

Method
drawBezierCurve(displayId : DisplayID, pointsObj : table, r : number, g : number, b : number, segmentsObj : number) : ()
drawRoundedRect(displayId : DisplayID, x : number, y : number, w : number, h : number, radius : number, r : number, g : number, b : number, filled : boolean) : ()
drawSVGPath(displayId : DisplayID, pathData : string, x : number, y : number, scale : number, r : number, g : number, b : number) : ()
drawStar(displayId : DisplayID, cx : number, cy : number, points : number, outerRadius : number, innerRadius : number, r : number, g : number, b : number, filled : boolean) : ()

Usage

drawBezierCurve

Draws a Bézier curve using a list of control points.

The pointsObj table should contain points in the following format:

{
    {x1, y1},
    {x2, y2},
    {x3, y3},
    {x4, y4}
}

segmentsObj controls curve smoothness. If omitted, DirectGPU uses a default segment count.

Requires: DisplayID, pointsObj : table, r : number, g : number, b : number

Example

gpu.drawBezierCurve(
    displayId,
    {
        {10, 80},
        {40, 10},
        {90, 10},
        {120, 80}
    },
    255,
    255,
    255,
    50
)

---

drawRoundedRect

Draws a rectangle with rounded corners.

Set filled to true to draw a filled rounded rectangle.

Requires: DisplayID, position, size, radius, color, and fill state.

Example

gpu.drawRoundedRect(
    displayId,
    10,
    10,
    100,
    40,
    8,
    0,
    200,
    255,
    true
)

---

drawSVGPath

Draws a shape from SVG-style path data.

Useful for rendering icons and custom vector graphics.

Supported path commands depend on the SVG parser implementation.

Requires:

• DisplayID
• pathData : string
• x : number
• y : number
• scale : number
• r : number
• g : number
• b : number

Example

gpu.drawSVGPath(
    displayId,
    "M 0 0 L 10 0 L 10 10 Z",
    50,
    50,
    4,
    255,
    255,
    255
)

---

drawStar

Draws a star shape.

points controls the number of star points.

outerRadius controls the outside points, while innerRadius controls the inner edges.

Set filled to true to draw a solid star.

Example

gpu.drawStar(
    displayId,
    80,
    80,
    5,
    30,
    15,
    255,
    255,
    0,
    true
)
