Function decFloat32Sequence

loader/collada/common.go:352–376

decFloat32Sequence receives a byte slice with float numbers separated by spaces and a preallocated destination slice. It reads numbers from the source byte slice, converts them to float32 and stores in the destination array.

(cdata []byte, dest []float32)

// It reads numbers from the source byte slice, converts them to float32 and
// stores in the destination array.

	idx := 0
	for {
		tok := br.TokenNext()
		if tok == nil {

		if idx >= len(dest) {
			return fmt.Errorf("To much float array data")

		v, err := strconv.ParseFloat(string(tok), 32)
		if err != nil {
			return err
