C++ (Cpp) safeLerp Examples

Example #1

File: AnimUtil.cpp Project: AndrewMeadows/hifi

void blend(size_t numPoses, const AnimPose* a, const AnimPose* b, float alpha, AnimPose* result) {
    for (size_t i = 0; i < numPoses; i++) {
        const AnimPose& aPose = a[i];
        const AnimPose& bPose = b[i];

        result[i].scale() = lerp(aPose.scale(), bPose.scale(), alpha);
        result[i].rot() = safeLerp(aPose.rot(), bPose.rot(), alpha);
        result[i].trans() = lerp(aPose.trans(), bPose.trans(), alpha);
    }
}

Example #2

File: AnimUtil.cpp Project: SeijiEmery/hifi

void blend(size_t numPoses, const AnimPose* a, const AnimPose* b, float alpha, AnimPose* result) {
    for (size_t i = 0; i < numPoses; i++) {
        const AnimPose& aPose = a[i];
        const AnimPose& bPose = b[i];

        // adjust signs if necessary
        const glm::quat& q1 = aPose.rot();
        glm::quat q2 = bPose.rot();
        float dot = glm::dot(q1, q2);
        if (dot < 0.0f) {
            q2 = -q2;
        }

        result[i].scale() = lerp(aPose.scale(), bPose.scale(), alpha);
        result[i].rot() = safeLerp(aPose.rot(), bPose.rot(), alpha);
        result[i].trans() = lerp(aPose.trans(), bPose.trans(), alpha);
    }
