🌈 DESCRIPTION 🌈

so this shape node builds triangle strips out of vertices. the vertices can come from the vertexProperty field (that one's inherited from SoVertexShape), or from the current inherited coordinates. and ngl, if you want optimal performance? use the vertexProperty field. trust. 💯

SoTriangleStripSet is literally one of the fastest ways to draw polygonal objects in Inventor. it takes the current coordinates, in order, starting with the very first one. the values in the numVertices field tell you how many vertices to use for each triangle strip in the set — and the number of values in that field is what determines the number of strips. periodt.

for example: if numVertices holds the values [3,5], then coordinates 1, 2, and 3 get used for the first triangle strip, and coordinates 4, 5, 6, 7, and 8 get used for the second strip. that gives you 1 triangle in the first strip and 3 in the second. math ate that 💅

the coordinates of the strips get transformed by the current cumulative transformation. the strips are drawn with the current light model and drawing style. no notes.

now, treatment of the current material and normal binding, bestie, listen up:

• the PER_PART binding specifies a material or normal for each strip of the set.
• the PER_FACE binding specifies a material or normal for each triangle.
• the _INDEXED bindings are equivalent to their non-indexed counterparts.
• the default normal binding is PER_VERTEX.
• the default material binding is OVERALL.

⚠️ if any normals (or materials) are specified, Inventor assumes you provide the correct number of them, as indicated by the binding. you WILL see unexpected results if you specify fewer normals (or materials) than the shape requires. 😭 don't do that to yourself.

if no normals are specified, they get generated automatically. she's self-sufficient 🧚

🍓 FIELDS 🍓

• SoMFInt32 numVertices — number of vertices in each triangle strip. the number of strips equals the number of values in this field. simple as that 💖

---

💜 METHODS 💜

• SoTriangleStripSet() — creates a triangle strip set node with default settings. a fresh baby node, born ready ✨
• static SoType getClassTypeId() — returns the type identifier for this class. it's giving ID card 🪪

---

🔥 ACTION BEHAVIOR 🔥

• SoGLRenderAction — draws a strip set based on the current coordinates, normals, materials, drawing style, and so on. the main character doing main character things 👑
• SoRayPickAction — picks on the strip set based on the current coordinates and transformation. details about the intersection come back in an SoFaceDetail. she's nosy and we love that 🙈
• SoGetBoundingBoxAction — computes the bounding box that encloses all vertices of the strip set, with the current transformation applied to them. it sets the center to the average of the coordinates of all vertices. centering, as always 💅
• SoCallbackAction — if any triangle callbacks are registered with the action, they get invoked for each successive triangle forming the strips of the set. every single one. no skipping. 🌸

---

⭐ FILE FORMAT/DEFAULTS ⭐

TriangleStripSet {
    vertexProperty  NULL
    startIndex      0
    numVertices     -1
}

look at those defaults. NULL, 0, -1. minimal, clean, unbothered 💖
